The library charges $2 to use the copier and $0.99 for each paid copied. if jerry paid the librarian $8.93 ,how many copies did he make

First subtract the 2 dollars then you will have 6.39 then divid by the .99 wich gives you 6.45 which you round up to 7 copious because you can’t have a 1/2 of a copy

We already know he paid $2 to use the printer, so you have your first equation: $8.93 - $2.00 = $6.98.

He has to pay $0.99 for each copy he prints. 

You just need to multiply $0.99 by however many times it takes to get close enough to $6.98.

When I did that, I got 7. 

7 was the closest answer I got. So Jerry made 7 copies of paper or printed 7 pages.

It is the top one. the answer is -7. that is smallest
