Question

A carpenter worked for 4 days to finish a repair job. She charged $825 for 15 hours plus $278 for material. What is the carpenter's rate per hour?

Answer 1

15x + 278 = 825
15x = 547
x = $36.47 / hour

Answer 2

Answer: His rate is $ 55 per hour plus $278 material charge.

Explanation:

According to the question,

Carpenter's charge free from material charge for 15 hours = $825

Thus, Her charge free from material charge for 1 hours =
`(825)/(15)`

=
`55`

Thus, She charged $55 for 1 hours plus $278 material.

Therefore, her rate per hour = $55 per hour plus $248 material charge.
