Answer:
15 dollars
Step-by-step explanation:
Store W charges 5 dollars for unlimited copies, so the number of copies does not matter for store W.
Because store W offers unlimited copies for $5, that will be the amount that store Z has to charge to be the same amount.
Now, we know that store Z charges you 2 dollars at the start for the use of the machine, so you subtract from the total amount from store W, 5 dollars.
5-2=3
So now you have 3 dollars to pay for the copies from store Z.
Each copy from store Z costs $.20.
Divide 3 by .20
3/.20=15
