Problema Solution
cds were purchased at $60 per dozen and sold at $30 for four cds. Find the profit on 9 dozen cds.
Answer provided by our tutors
1 dozen = 12
The purchase cost for 9 dozen cds is:
$60*9 = $540
Cost = $540
9 dozen = 9*12
The revenue from 9 dozen cds is 30*(9*12/4) = $810
Revenue = $810
Profit = Revenue - Cost
Profit = $810- $540
Profit = $270
The profit on 9 dozen cds is $270.
