Respuesta :

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
