Answer:
Mechanic A
$85 per hour of labor
$255
Explanation:
The table below shows the labor costs for different mechanics that Mikayla has visited.
[tex]\left|\begin{array}{c|c}$Mechanic&$Labour Prices\\---&--------\\A&\$276.25 for 3.25 hours\\B&\$285 for 3 hours\\C&\$304.50 for 3.5 hours\\D&\$405 for 4.5 hours\end{array}\right|[/tex]
We calculate the unit rate for each mechanic below.
[tex]\left|\begin{array}{c|c}$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|[/tex]
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
