Question

iden has $15.00 on his copy card. Each time he uses the card to make a photocopy, $0.06 is deducted from his card. Aiden wants to be sure that there will be at least $5.00 left on his card when he is finished. The inequality below relates x, the number of copies he can make, with his copy card balance.

15 minus 0.06 x greater-than-or-equal-to 5

What is the maximum number of copies Aiden can make?
60
83
166
250

Answer 1

Solve 15 − 0.06x ≥ 5:
15 − 5 ≥ 0.06x → 10 ≥ 0.06x → x ≤ 10 / 0.06 = 166.666...
He can make at most 166 whole copies.

Answer: 166
