Last week a jacket cost $39.50. This week the price of the jacket decreased by $4.50. What was the percent of the decrease? Round to the nearest tenth.

Answers

Answer 1

it might be 0.11 or 0.12%

Answer 2

First, let's create an equation for this problem. Let x represent the percent decrease.
[tex] \frac{4.50}{39.50} [/tex] = [tex] \frac{x}{100} [/tex]

Next, cross multiply.
39.50x = 450

Now, all you would need to do is isolate the x. To do this, you would divide both sides of the equal sign by 39.50.
x = 11.3924050633

Remember to round the answer to the nearest tenth.
11.3924050633 ≈ 11.40%

The percent decrease is 11.40%.

I hope this helps!

Professor Bartlett teaches a class of 12 students. She has a visually challenged student, Louise, who must sit in the front row next to her tutor, who is also a member of the class. Assume that the front row has seven chairs, and the tutor must be seated to the right of Louise. How many different ways can Professor Bartlett assign students to sit in the first row

Answers

Final answer:

Professor Bartlett can arrange the students in 1,440 different ways in the first row, considering Louise must sit next to her tutor on the right.

Explanation:

Professor Bartlett teaches a class of 12 students and needs to seat them in the front row which consists of 7 chairs. Specifically, Louise, who is visually challenged, must sit next to her tutor on the right side. To determine the number of different ways the students can be seated in the first row, we first consider the places of Louise and her tutor. Since Louise's tutor must be seated to her right, they can be viewed as a single entity with two internal arrangements: Louise on the left and the tutor on the right. Therefore, there are now effectively 6 entities to arrange (Louise and her tutor considered as one, plus the 5 other students) in 6 chairs in the front row.

The number of ways to arrange 6 entities in 6 spots is calculated by 6 factorial (6!), which equals 720. However, since Louise and her tutor can switch places within their designated spot, we must multiply this number by the 2 internal arrangements possible, resulting in 720 * 2 = 1,440 different seating arrangements for the first row.

maggie has only dimes and quarters in her purse. she has 27 coins with a total value of 4.05. how many dimes does maggie have in her purse

Answers

d + q = 27.....q = 27 - d
0.10d + 0.25q = 4.05

0.10d + 0.25(27 - d) = 4.05
0.10d + 6.75 - 0.25d = 4.05
0.10d - 0.25d = 4.05 - 6.75
-0.15d = - 2.70
d = -2.70/ - 0.15
d = 18 <=== Maggie has 18 dimes
and (27 - 18) = 9 quarters

By solving a system of equations, we will see that Maggie has 18 dimes and 9 quarters.

How to write the system of equations?

First, we define the variables that we will use:

D = number of dimes.Q = number of quarters.

There are a total of 27 coins, so:

Q + D = 27.

The total value is 4.05, so:

Q*0.25 + D*0.10 = 4.05

Then our system of equations:

Q + D = 27

Q*0.25 + D*0.10 = 4.05

To solve this we need to isolate one of the variables in one of the equations, I will isolate Q in the first one.

Q = 27 - D

Now we can replace this on the other equation and solve it for D:

(27 - D)*0.25 + D*0.10 = 4.05

6.75 - D*0.25 + D*0.10 = 4.05

6.75 - D*0.15 = 4.05

6.75 - 4.05 = D*0.15

2.70 = D*0.15

2.70/0.15 = D = 18

So she has 18 dimes, and then the other 9 conis must be quarters.

A grocery store bought milk for $2.20 per half gallon and stored it in two refrigerators. During the night, one refrigerator malfunctioned and ruined 13half gallons. If the remaining milk is sold for $4.04per half gallon, how many half gallons did the store buy if they made a profit of $116.76?

Answers

Total of 92 half gallons of milk they bought.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say they bought x half a gallon of milk.

Cost of buying ⇒

x × 2.20 = 2.2x

Since 13 half gallons were destroyed so

Remaining = x - 13

The selling price of remaining milk ⇒

(x - 13) × 4.04

Now,

Profit = selling price - cost of buying.

116.76 = (x - 13) × 4.04 - 2.2x

4.04x - 2.2x - 52.52 = 116.76

1.84 x = 169.28

x = 92

Hence "Total of 92 half gallons of milk they bought".
