Question

A taxi charges a flat fee of 4.00 plus 2.25 per mile. How much will the taxi driver earn if he takes one passenger 4.8 miles and another passenger 7.3 miles?

Answer 1

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.
