Question

Stela rents a car for business trip. Flat rate is $60 plus $0.50 per mile over 40 miles. Company pays $270 for trip. How far can she drive without going over $270.

Answer 1

60 + 0.50(x - 40) < = 270

60 + 0.50x - 20 < = 270

40 + 0.50x < = 270

0.50x < = 270 - 40

0.50x < = 230

x < = 230/0.50

x < = 460 miles
