Calculators were purchased at $65 per dozen and sold at $20 for 3. How much profit was made on six dozen calculators?
Answer provided by our tutors
cost per calculator:
65 / 12
revenue per calculator:
20/3
profile per calculator:
profit = revenue - cost = (20/3) - (65/12) = 1.25
profit made on six dozen calculators:
6*12*1.25 = 90
$90 profit would be made on 6 dozen calculators
