Answer
The profit on six dozen calculators is $90.00
Work Step by Step
The store purchased the calculators at 65 dollars for 12 calculators. They sold them at 20 dollars for 3 calculators. This would be 80 dollars when 12 calculators are sold —
3 calculators sell for 20 dollars
6 calculators would then sell for 40 dollars
So, 12 calculators would sell for 80 dollars.
The profit on one dozen (12) calculators is:
80 - 65 = 15
So for one dozen calculators, the store profits 15 dollars. For six dozen calculators, the store will profit 6 x 15 which is 90 dollars.
Therefore, the profit on six dozen calculators is 90 dollars,
