Question

Yamil purchased a copy machine for $2100 and a one-year maintenance protection plan that costs 2 cents per copy made. If he spends a total of $2462 in a year, which includes the cost of the machine and the copies made, determine the number of copies he made

Answer 1

You would subtract $2462 - $2100 to get the remaining amount of money spent on copies, which is $362. You then divide $362 by the amount each copy costs, which is $0.02. So $362/0.02 = 18100 copies.

Answer 2

Let "x" be the number of copies made.

Total cost = (cost of machine) + (cost of maintenance plan)

Total cost = ($2100) + (0.02x)

2462 = 2100 + 0.02x

362 = 0.02x

362/0.02 = x

18100 = x

18,100 copies were made
