Question
The shop owner pays $1.76 for each spark plug. The owner pays 40% off list price for
all other materials. What is the shop owner's profit on parts? $_
(Round to the nearest whole cent)
82.08
Multiply the cost of the spark plug ($1.76) by the number of plugs (8) to find
the cost of the plugs. Add the rest of the items and multiply by .6 (100% of sale
price - 40% shop discount = 60% shop cost). Add this number to the cost of
the plugs to find total shop cost for parts. Subtract this from total customer
cost (not including labor) to find parts profit.
