Question

a certain atore has a fax machine available for use by its customers. the store charges $2.30 to send the first page and $0.40 for each subsequent page. use an inequality to find the maximum number of pages that can be faxed for $5.10

Answer 1

2.30 + 0.40(x - 1) < = 5.10
2.30 + 0.40x - 0.40 < = 5.10
1.90 + 0.40x < = 5.10
0.40x < = 5.10 - 1.90
0.40x < = 3.20
x < = 3.20 / 0.40
x < = 8 <=== 8 pages, at the most, can be faxed
