Final answer:
At a rate of $0.50 per copy, 56 copies could be made for $28 at the local print shop.
Step-by-step explanation:
If 14 copies can be made for $7, then we can find the rate per copy by dividing the total cost by the number of copies. This gives us $7 / 14 copies = $0.50 per copy. To find out how many copies can be made for $28, we divide the total amount of money by the cost per copy: $28 / $0.50 per copy = 56 copies. Therefore, 56 copies could be made for $28 at this rate.
