Question

Alonso paid for repairs on his car, and 3/5

of the bill was for labor costs. How much was the total bill if the cost of the labor was $79.50? Let b = the amount of the total bill.
Which equation and solution is correct?

Answer 1

Answer: D

:Three-fifths (b) = 79.50, and the total bill was $132.50.

Answer 2

so 3/5 of the total bill was for labor....and labor costs are 79.50...
so 3/5b = 79.50

3/5b = 79.50
b = (79.50) / (3/5)
b = 79.50 * 5/3
b = 397.50/3
b = 132.50 <=== total bill
