for his phone service, miguel pays a monthly fee of $29, and ge pays an additional $0.07 per minute of use. the least he has been charged in a month is $110.48

Question

Write as an inequality

Answer 1

110.48 > 29 + .07m

80.52 > .07m

80.52/.07 > m

m < 80.52/.07 = about 1151 minutes per month minimum

Answer 2

m is defined as no. of minutes used per month.

The total consists of a flat monthly fee ($29) plus (variable) charges based on usage ($0.07/min)

Total is at least $110.48/mo.

29 + 0.07m ≥ 110.48
