Answer 1

29. A carpenter worked for 4 days to finish a repair job. She charged $825 for 15 hours plus $278 for materials. What is the carpenter's rate per hour? Let’s start solving: => 825 dollars + 278 dollars = 1 103 dollars is the total payment a carpenter have received => 15 hours is the total hours he worked => 1 103 / 15 = 73.5 dollars per hour. This is already including the material or equipment fee.

Answer 2

Answer:  Carpenter's rate per hour is $73.53.

Step-by-step explanation:

Since we have given that

Number of hours she charged for = 15 hours

Cost for 15 hours = $825

Cost of materials = $278

Total cost she charged is given by

$\ 825+\ 278\\\\=\ 1103$

So, Carpenter's rate per hour is given by

$\frac{Total\ amount}{Number\ of\ hours}\\\\=\frac{1103}{15}\\\\=\ 73.53$

Hence, Carpenter's rate per hour is $73.53.
