Question

Mechanic

Answer 1

Answer:

Mechanic A

$85 per hour of labor

$255

Explanation:

The table below shows the labor costs for different mechanics  that Mikayla has visited.

$\left|\begin{array}{c|c} Mechanic& Labour Prices\\---&--------\\A&\ 276.25 for 3.25 hours\\B&\ 285 for 3 hours\\C&\ 304.50 for 3.5 hours\\D&\ 405 for 4.5 hours\end{array}\right|$

We calculate the unit rate for each mechanic below.

$\left|\begin{array}{c|c} Mechanic& Labour Prices\\---&--------\\A&\ 276.25 \div 3.25 hours=\ 85 per hour\\B&\ 285 \div 3 hours =\ 95 per hour\\C&\ 304.50 \div 3.5 hours=\ 87 per hour\\D&\ 405 \div 4.5 hours=\ 90 per hour\end{array}\right|$

Based on the data in the table Mikayla should return to  Mechanic A for her next repairs .

This mechanic charges $85 per hour of labor

An average repair takes 3 hours. Therefore the amount Mikayla would pay  this mechanic for these repairs is:

3*$85=$255
