Question

A Plumber fixed a leaky sink and charge $60 for parts and $50 per hour for labor. The total bill was $285. Write down an equation that can be used to find how many hours (h) the plumber spent fixing the sink.

Answer 1

285 = 50h + 60; 4.5 hours

Explanation:

$50 per hour - 50h

$60 for parts - 60

$285 total

285 = 50h + 60

225 = 50h

h = 4.5

The plumber worked for 4.5 hours to fix the leaky sink
