Question

A painter charges $225 for materials and $35 per hour for labor. The total cost of painting an office is $330 how many hours did it take the painter to paint the office?

Answer 1

the painter takes 3 hours to paint the office

Answer 2

The time taken by the painter is 3 hours.

Given data :

Material cost = $225

Labour cost = $35/hour

Total cost = $330

So,

The total labour cost = (330-225) = $105

Now,

$35 is required for = 1 hour

$1 is required for = 1/35 hour

$105 is required for = 105/35 = 3 hours (answer)
