Final answer:
To find the cost of copies, multiply the number of copies by the price per copy. In this case, the cost of the copies is $9.80.
Step-by-step explanation:
To calculate the cost of the copies, you can multiply the number of copies by the price per copy. In this case, you are making $140 copies and the shop charges 7 cents for each copy. To find the cost, you would multiply $140 by 7 cents (or 0.07 dollars).
Cost of copies = Number of copies x Price per copy
= $140 x $0.07
= $9.80
Therefore, the cost of the copies is $9.80.
