Romeo buys five bars of chocolate at $5 each and sells these chocolates for a total of $90. If he uses packaging material that costs him $2 for each bar of chocolate, how much profit does he make for all the chocolates he sells?
The selling price for each bar of chocolate is 90/5=$<<90/5=18>>18.
The profit for each bar of chocolate is 18-5-2=$<<18-5-2=11>>11.
The total profit is 11*5=$<<11*5=55>>55.
