You decide to sell each of your toys for $25. Costs are how much you pay your supplier ($11 to make each toy plus a one-time fee of $18 for shipping) Earnings are how much money you earn before subtracting out any costs ($25 per toy) Profit = Earnings `-` Costs
Fill out the table. The last row should include the maximum number of toys you are able to sell. Your maximum number of toys is the solution you found in #2. Multiply by 25 to get your earnings. Multiply by 11 and add 18 to get your cost.
