Problema Solution
Pens are bought at 0.95 per dozen and sold in groups of four for $2.25. Find the profit on 15 dozen pens?
Answer provided by our tutors
The cost of 15 dozen pens is: 0.95*15 = $14.25
The revenue from selling 15 dozen pens is: 2.25(15*12/4) = $101.25
Profit = Revenue - Cost
Profit = 101.25 - 14.25
Profit = $87
The profit in 15 dozen pens is $87.
