Answer

Explanation:

Step1: Find the cost per copy

We know that it costs $1 to make 5 copies. The cost per copy $c$ is calculated by dividing the total cost by the number of copies. So $c=\frac{1}{5}= 0.2$ dollars per copy. We can double - check with the second data point: when it costs $5 to make 25 copies, $c=\frac{5}{25}=0.2$ dollars per copy.

Step2: Calculate the cost for 100 copies

To find the cost $C$ for 100 copies, we multiply the cost per copy by the number of copies. Using the formula $C = c\times n$, where $c = 0.2$ and $n = 100$. So $C=0.2\times100 = 20$ dollars.

Answer:

B. $20
