Answer:

Cost of one apple is #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) #=ntimes(0.40/3)#

n stands for number of apples

#10times3 = 0.40timesn#

#30/0.40 = n#

#75 = n#

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