Solution: Cost price of 1,000 fans = $ (15 * 1000) = $15,000
=> Number of fans sold at $20 each = \(\frac{40}{100}\cdot1,000=400\)
=> Thus, selling price of these 400 fans = $(400 * 20) = $8,000
=> Number of fans sold at $ 30 each = 1000 – 400 = 600
=> Thus, selling of these 600 fans = $(600 * 30) = $18,000
=> Total selling price of 1,000 fans = $8,000 + $18, 000 = $26,000
=> Total profit: Selling price – Cost price = $26,000 - $15,000 = $21,000
=> Profit per fan:$ \(\frac{21,000}{1,000}\) = 21
Therefore, D is the correct answer.
Answer D
=> Number of fans sold at $20 each = \(\frac{40}{100}\cdot1,000=400\)
=> Thus, selling price of these 400 fans = $(400 * 20) = $8,000
=> Number of fans sold at $ 30 each = 1000 – 400 = 600
=> Thus, selling of these 600 fans = $(600 * 30) = $18,000
=> Total selling price of 1,000 fans = $8,000 + $18, 000 = $26,000
=> Total profit: Selling price – Cost price = $26,000 - $15,000 = $21,000
=> Profit per fan:$ \(\frac{21,000}{1,000}\) = 21
Therefore, D is the correct answer.
