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

Explanation:

Step1: Find cost per copy for 25 copies

To find the cost per copy when making 25 copies, we use the formula $\text{Cost per copy} = \frac{\text{Total cost}}{\text{Number of copies}}$. For 25 copies costing $5, the cost per copy is $\frac{5}{25} = 0.2$ dollars per copy.

Step2: Calculate cost for 100 copies

Now, to find the cost for 100 copies, we use the formula $\text{Total cost} = \text{Cost per copy} \times \text{Number of copies}$. Substituting the values, we get $0.2\times100 = 20$ dollars.

Answer:

B. $20
