Write an equation. T = Total money made M = miles driven 4 + 2.25m T = 7.3*2.25 + 4 + 2.25*4.8 + 4 T = 8 + 7.3*2.25 + 2.25 * 4.8 4.8 * 2.25 = 10.8 7.3 * 2.25 = 16.425 T = 16.425 + 8 + 10.8 T = 35.225 So, the total amount of money he made was $35.25.
The math I used is probably not the quickest way, but for me, the easiest. 25*5=125 25+20=45 45*7=315 125+315=440 25*4=100 440+100=540 5+7+4=16 B is your answer.
