Since both the key information provided and the correct answer are in percentage terms, we can ignore the original price of 80 cents per pound and either calculate a weighted average percent profit or use smart numbers to arrive at an answer.
A weighted average percent profit could be calculated as follows:
(.20 × 100%) + (.80 × .80 × 50%) + (.16 × -100%) = 20% + 32% - 16% = 36%
Using smart numbers, we can solve the problem as follows:
Original cost: 100 for 100 pounds, meaning $1 per pound
20 pounds sold at 200% of original cost: 20 × 2 = 40
80 percent of 80 pounds sold at 150% percent of original cost: 64 × 1.5 = 96
16 pounds never sold: 0
(40 + 96 + 0 - 100/100) × 100 = 36%
(A) 36%
(B) 42%
(C) 52%
(D) 60%
(E) 80%
