Step-by-step explanation:

It took the mechanic an hour and a half so 1.5 hour.

Step-by-step explanation:

If the mechanic charges $30 per hour + $45 for parts=75. If the total cost was $90 then 90(total cost)-75(for the first hour +parts) =15 and 30(cost of one hour)/2 is 15 which is half hour.

3 1/3 x 2 3/5 = 8 2/3

just multiply the first number by the second number to get your answer.
