Cost of one apple is $\frac{0.50}{3}$ $0.50/3$ . selling price is $$ .30$ $$.30$ . She has to sell 75 apples to make 10 dollar profit.

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 - ($ \frac{0.50}{3})$ $=$0.30-($0.50/3)$ (after selling one apple)

Net profit $= $ \frac{0.40}{3}$ $=$0.40/3$ (from one apple)

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

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

n stands for number of apples

$10 \times 3 = 0.40 \times n$ $10times3 = 0.40timesn$

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

$75 = n$ $75 = n$

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