A store sells 12-packs of ballpoint pens for $1.09 each and composition books for $2.79 each. Cindy buys m packs of ballpoint pens and n composition books. The store offers a 5% discount for every 50th customer who makes a purchase. If Cindy gets the 5% discount, which expression will represent Cindy’s bill?
0.05 − 1.09m + 2.79n
1.05 + 1.09m + 2.79n
1.05(1.09m + 2.79n)
0.95(1.09m + 2.79n)
Answer: The expression that represents Cindy´s bill is 0.95(1.09m + 2.79n).
Step-by-step explanation:
Hi, to find the correct expression we have to analyze the information given:
Packs of ballpoint pens = m
Price of ballpoint pens=$1.09 each
Composition books= n
Price of composition books = $2.79 each
Discount 5%
Cindy buys m packs of ballpoint pens and n composition books. To represent this statement in an equation we have to multiply each quantity of the items bought by the price of each item.
So, mathematically speaking
1.09m + 2.79n
Now, to apply the 5% percent discount we have to multiply the whole expression by 0.95.
0.95(1.09m + 2.79n)
In conclusion, the expression that represents Cindy´s bill is 0.95(1.09m + 2.79n).

the sales tax in one town is 8%. so the total cost of an item can be written as c+0.08c. What is the total cost of an item that sells for $12
The total cost of an item that sells for $12 with an 8% sales tax is calculated by multiplying the price by the sales tax rate to get the sales tax amount, which is then added to the original price. The total cost comes out to $12.96.
To find the total cost of an item that sells for $12 with an 8% sales tax, you need to first convert the sales tax rate to a decimal and then multiply by the cost of the item. In this case, 8% as a decimal is 0.08.
The formula to calculate the amount of sales tax is:
Amount of sales tax = price ×rate of sales tax
So for a $12 item:
$12 ×0.08 = $0.96
This is the amount of sales tax for the item. To find the total cost, you have to add the sales tax to the original price:
$12 + $0.96 = $12.96

Maya collects stamps she has 20 stamps in her collection four fifths of her stance have been cancelled how many of the stands and collection has been cancelled
Maya has 20 stamps in her collection, and four-fifths of them have been canceled. Therefore, 16 stamps in Maya's collection have been canceled.
Maya has 20 stamps in her collection, and four-fifths of them have been canceled. To find out how many stamps have been canceled, you would multiply the total number of stamps by the fraction that has been canceled.
Calculate 4/5 of 20 stamps: 20 x 4/5 = 16 stamps.
Therefore, 16 stamps in Maya's collection have been canceled.
6 times 6 plus 3 times 3 times 2 thirds

Can be used to organize function values?
The question explores how to organize function values, highlighting the definition and uniqueness of functions in mathematics. Functions can be represented through tables, graphs, and formulas, facilitating the understanding of complex relationships between inputs and outputs. The concept also ties into broader mathematical principles, exemplifying the importance of functional representation in logical and analytical reasoning.
Explanation:Can be used to organize function values? The concept of organizing and managing function values is central in mathematics, especially when dealing with functions in algebra and calculus. A function is essentially a set of ordered pairs, where each element in the domain (input) is associated with exactly one element in the range (output). This uniqueness criteria distinguish a function from a general relation. For instance, a set containing pairs like (3,2) and (5,2) represents a valid function since each input maps to a single output, even if multiple inputs share the same output.
Functions can be organized or represented in multiple ways, including tables, graphs, formulas, or mappings of inputs to outputs as seen in function B, where arguments (inputs) are mapped onto unique values (outputs). This method emphasizes the power of function composition where functions call other functions, enriching the idea that mathematics often builds up complex ideas from simpler ones.
Furthermore, the versatility of functions allows them to encapsulate broader concepts, illustrated by the characteristic function of a set, showcasing how functional representation can offer a more convenient and general approach compared to set membership. This approach is significant in various mathematical fields, including the functional analysis of set theories and logic, underlining the functional representation's impact on understanding and interpreting rules.

what are the partial products of 4.6 x
3.5
The partial product of 4.6 and 3.5 is calculated by breaking each number into whole numbers and decimals, multiplying each part separately, resulting in 16.1 as the product.
Explanation:Partial products is a method in multiplication. It involves the breaking down of numbers into their place values and then multiplying each part separately. For 4.6 x 3.5, first split the numbers into their whole numbers and decimal parts: 4 + 0.6 and 3 + 0.5.
Then, calculate the products individually:
4 x 3 = 124 x 0.5 = 20.6 x 3 = 1.8 0.6 x 0.5 = 0.3Add these partial products together:
12 + 2 + 1.8 + 0.3 = 16.1
So, the product of 4.6 x 3.5 through partial products is 16.1.

Jackie wants to buy a new CD player. It costs $32.95. She has saved $26 and has a new coupon for %30 off the price. Does Jackie have enough money to buy the CD player?
Answer:
The correct answer is Yes, she has enough money to buy the CD player.
Step-by-step explanation:
First we must analyze the information we have:
We know that Jackie has saved $ 26 to buy a CD that costs $ 32.95.
In principle we could say that she does not have enough money. But she has a 30% discount coupon.
Now we must find out if with that she will have enough money to pay for the CD.
For that we must know how much money she got off.
And we will do it as follows:
Discount coupon: 32, 95. 0.30
Discount coupon: 9.88
Now we know that the total CD was discounted $ 9.88.
We just have to do the subtraction:
32.95 - 9.88 = 23.07
Therefore, we can say that Jackie will have enough money to buy the CD player.
