.a store sold A at a price three times as much as B. The gross profit of A is 80% of the price that the store paid for A. The gross profit for B is 20% of the price that the store paid for B. what percent is the total gross profit of the total amount that the store paid for both A and B?
I may have overcomplicated it but here goes:
Let x = price the store paid for A
Selling price of A = 1.8x
Selling price of B = 1/3 of A = 0.6x
Selling price of B = 120% of price paid for B or 1.2B or 6/5B
Price store paid for B = 5(0.6x)/6 = 0.5x
Gross profit of A = 1.8x - x = 0.8x
Gross profit of B = 0.6x - 0.5x = 0.1x
Total gross profit = 0.8x+0.1x = 0.9x
Total amount store paid for A+B = x+0.5x = 1.5x
% of total gross profit from A+B over amount paid for A+B=
100(0.9x/1.5x)
= 60%
