Question

It costs $3.56 to buy a pack of pencils. Which of the following equations shows the amount of money needed, x, to buy k packs of pencils?

x = 3.56k
k = 3.56x
x = 3.56 + k
k = 3.56 + x

Answer 1

x = 3.65k.

Explanation:

Answer 2

Well, since we know $3.65 is how much ONE PACK of pencil costs, and k represents the packs of pencils PURCHASED, and x represents the COST per pack, your answer would be A. x = 3.65k. This is because to find out the total cost (x) of k amount of packs, you would multiply the cost (3.65) times k, (known as 3.65k), which would be expressed as x = 3.65k. =)
