Question

Tony wants to start making and selling skateboards. His costs are the large sum of money that includes his initial investment and the cost of materials for each skateboard. He has already planned how much he is going to sell his skateboards for. Explain how Tony can set up a system of equations to predict when he will start to make a profit.

Answer 1

For clear understanding (profit on each item) multiplied by the total number of items will give the total gain
and actual profit is (total gain - Investment)

P=n(C-S)-I
P=total profit
N=number of items
I=initial investment
S=selling price of each item
