Question

Sam buys 10 apples for $1. At what price should he sell a dozen apples if he wishes to make a profit of 25%?​

Answer 1

Answer:

• The cost price of 1 apple = 1/10th of a dollar or $0.10.
• As Sam wishes to make a profit of 25%, his selling price per apple will be 0.10 + 25% of 0.10 = $0.125.
• If the selling price of 1 apple is $0.125, then the selling price of a dozen apples = 12 * 0.125

= $1.5
