Cost of one apple is $\frac{0.50}{3}$. selling price is $.30. She has to sell 75 apples to make 10 dollar profit. #### Explanation: Let me compute the net profit when she sells only one apple. It is the difference between selling price and cost Net profit =$0.30-($0.50/3) (after selling one apple) Net profit =$0.40/3# (from one apple)

How many apples should she sell to make 10 dollar profit?

Total profit (which is 10 dollars) $= n \times \left(\frac{0.40}{3}\right)$

n stands for number of apples

$10 \times 3 = 0.40 \times n$

$\frac{30}{0.40} = n$

$75 = n$

She has to sell 75 apples to make 10 dollars profit.
