Question

Select the correct answer. Sarah wants to print copies of her artwork. At the local print shop, it costs her $1 to make 5 copies and $5 to make 25 copies. How much would it cost Sarah to make 100 copies? A. $15 B. $20 C. $25 D. $30

Answer 1

Answer: B

Explanation:

$1 -> 5 copies, it's 20 cents per copy because $1 / 5 = 0.2

$5 -> 25 copies, it's 20 cents per copy because $5 / 25 = 0.2

So 100 copies * 20 cents = $20

Answer 2

$1 = 5copies means

$5 = 25 copies obviously

then

$x = 100 copies

100 / 5 = $x

so she needs

$20
