Question

Cellular phone service that charges per-minute will charge $70 for 270 minutes. How much would 1260 minutes cost? Round your answer to the nearest tenth.

Answer 1

$70 = 270 min
x = 1260 min
Where x is the charge of phone service per 1260 min.

Cross multiply:
1260 * 70 = 270 * x
88200 = 270x
88200/270 = x
x = 326.67

The total charge of cellular phone service for 1260 min is $326.67
