Answer:
A). $(55 + 20w + p)
B). $180.50
Step-by-step explanation:
A). Fees to inspect a car = $55
Per hour charges for any work = $20
Therefore, charges of 'w' hours of work = $20w
Cost of parts = $p
Total cost of a repair job = $(55 + 20w + p)
B). If w = 2.5 hours and p = $75.50
From the expression,
Total cost of the work = $[55 + (20×2.5) + 75.50]
= $(55 + 50 + 75.50)
= $180.50
