A. Julia would make $1150 profit after paying all expenses after the first game. And then she would make $1721.22 for the rest of the games. Since she will be clearing her number of $1000 profit per game, she should lease the booth.

The factor that constraints her from borrowing even more money is the total area of space that the warming oven can hold of hot dogs, pizza and BBQ sandwiches.
C. Yes, this is something she can reasonably do, since she is making a profit of $1721.22 a game $100 would not be hard to pay for some help. And she should definitely do this because she needs to make a total of 784 hot dogs before the game and before half time.
