If the consumer price index changes from 125 in september to 150 in october, what is the rate of inflation?
a. 20.0%
b. 16.7%
c. 9.1%
d. 45.5%
If the consumer price index changes from 125 in september to 150 in october, the rate of inflation is a. 20.0%
Further explanationInflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When inflation is too high, it is not good for the economy or individuals. Inflation always reduce the value of money, unless interest rates are higher than inflation. The less chance there is that savers will see the real return on their money if the inflation gets higher. There are causes of inflation such as demand-pull and Cost-push. They are responsible for a general rise in prices in an economy.
Policies to reduce inflation are such as monetary policy (Higher interest rates), Tight fiscal policy (Higher income tax and/or lower government spending that will reduce aggregate demand and leading to lower growth and less demand pull inflation).
The rate of inflation = 20%.
September's price = 125
October's price = 150
Rate of inflation = [tex]\frac{(150-125)}{125} * 100[/tex]
[tex]\frac{25}{125 } *100[/tex]
[tex]=0.2 * 100 \\= 20%[/tex]

Part A (4 points): Tonya selected a pair of shoes for the regular price of $80. How much money will she save by using the 20% off coupon? Justify your answer using equations, models, and/or words to explain your mathematical reasoning. I need the answer and the model and how you got the answer by tomorrow, Thx. :) Will Medal!
20% = 0.20
multiply original price ( $0) by 0.20 for the amount of discount then subtract it
80*0.20 = 16.00
she will save $16
80-16 = 64
she will pay $64 after the discount

Solve: log4(7t + 2) = 2
Answer:
The required value of t is equal to 2
Step-by-step explanation:
We need to solve the following expression :
[tex]\log_4(7t+2)=2[/tex]
Now, using the base rule :
[tex]2=\log_4(4^2)\\\\\implies 2= \log_4(16)[/tex]
Now, using this value of 2
[tex]\log_4(7t+2)=2\\\\\implies\log_4(7t+2)=\log_4(16)\\\\\implies 7t+2=16\\\\\implies 7t=16-2\\\\\implies 7t=14\\\\\implies t = 2[/tex]
Hence, The required value of t is equal to 2

Percy paid 24.10 for a basketball. The price of a basketball was 22.99. What was the sales tax rate?
Answer: The required sales tax rate is 4.83%.
Step-by-step explanation: Given that Percy paid 24.10 for a basketball and the price of a basketball was 22.99.
We are to find the sales tax rate.
According to the given information, the sales tax is given by
[tex]S.T.=24.10-22.99=1.11.[/tex]
Therefore, the sales tax rate is given by
[tex]\dfrac{1.11}{22.99}\times100\%=\dfrac{111}{22.99}\%=4.83\%.[/tex]
Thus, the required sales tax rate is 4.83%.

What is the monthly payment on $13,300 financed at 7.9 percent for 4 years if the monthly payment per $100 is $2.74?
A. $133
B. $364.42
C. 328.51
D. $284.44
Answer:
The monthly payment is $364.42
B is correct
Step-by-step explanation:
The monthly payment on $13,300 financed at 7.9 percent for 4 years.
If the monthly payment per $100 is $2.74
Financed amount = $13,300
We are given monthly payment for $100 is $2.74
It means we pay $2.74 for $100.
Now we find how many number of $100 in $13,300
Number of $100 in $13,300 [tex]=\dfrac{13300}{100} = 133[/tex]
133 number of hundred in $13,300
For each $100 monthly payment = $2.74
For 133 payment = 133 x 2.74
Monthly Payment for $13,300 finance = $364.42
Hence, The monthly payment is $364.42
(a) Use Euclid’s algorithm to find the g , the greatest common divisor of 273 and 3019.
Final answer:
To find the greatest common divisor of 273 and 3019 using Euclid's algorithm, we divide the larger number by the smaller and use the remainder to repeat the process until we reach a remainder of 0. The gcd of 273 and 3019 is determined to be 1, indicating that they are coprime.
Explanation:
Using Euclid's Algorithm to Find the GCD
Euclid's algorithm is a method to determine the greatest common divisor (gcd) of two numbers. To find the gcd of 273 and 3019, we perform the Euclidean division repeatedly until we get a remainder of zero. The last non-zero remainder will be the gcd of the given numbers.
Divide 3019 by 273 to get a quotient of 11 and a remainder of 46.
Next, divide 273 by 46 to get a quotient of 5 and a remainder of 43.
Then, divide 46 by 43 to get a quotient of 1 and a remainder of 3.
Finally, divide 43 by 3 to get a quotient of 14 and a remainder of 1.
Now, divide 3 by 1 to get a quotient of 3 and a remainder of 0.
Since the last non-zero remainder is 1, the greatest common divisor (gcd) or g of 273 and 3019 is 1. Thus, 273 and 3019 are coprime or relatively prime to each other.

A machine laying underground cable can place 125 meters of cable in 5 minutes What is the rate per minute
divide 125 by 5
125 /5 = 25 meters per minute
Answer:
The rate per min is, 25 meters/minute
Step-by-step explanation:
Unit rate is defined as when rates are expressed as a quantity of 1, such as 4 feet per second or 6 miles per hour, they are called unit rates.
Given the statement: a machine laying underground cable can place 125 meters of cable in 5 minutes.
Then by definition:
rate per minute = [tex]\frac{125}{5} = 25[/tex] meters /minute
therefore, the rate per minute is, 25 meters/ minute

When we toss a penny, experience shows that the probability (long term proportion) of a head is close to 1-in-2. suppose now that we toss the penny repeatedly until we get a head. what is the probability that the first head comes up in an odd number of tosses (one, three, five, and so on)?
The probability that the first head comes up in an odd number of tosses can be determined using geometric probability.
Explanation:When tossing a coin repeatedly until we get a head, the probability that the first head comes up in an odd number of tosses can be determined using geometric probability. Since the probability of getting a head in one toss is 0.5, the probability of getting a head in an odd number of tosses (one, three, five, etc.) can be calculated using the formula:
P(odd number of tosses) = P(tail) * P(tail) * P(tail) * ... * P(head)
The number of terms in the product is determined by the number of tosses required to get the first head. For example, if it takes 3 tosses to get the first head, the formula becomes:
P(odd number of tosses) = P(tail) * P(tail) * P(head)
Since the probability of getting a tail is 0.5 and the probability of getting a head is also 0.5, the formula simplifies to:
P(odd number of tosses) = 0.5 * 0.5 * 0.5 * ... * 0.5 = (0.5)^n
Where 'n' is the number of tosses required to get the first head.

A number changed to 12.6 after it was rounded. To what place waa the number rounded? Explain how you know
Answer:
The number round to nearest tenths.
Step-by-step explanation:
Given : A number changed to 12.6 after it was rounded.
To find : To what place was the number rounded?
Solution :
The number round when the last digit place value is greater than 5, then before that number rounds by 1 and change the number.
In number 12.6 it was rounded to the nearest tenths.
Which means the hundredths place is greater than 5 either 6,7,8 or 9 and the tenths place is definitely 5.
So, the number can be 12.56, 12.57, 12.58, 12.59
If they all round we get the number 12.6.
