Your cost for each ice cream cone is $0.79 plus you have to pay a fee of $120 each week for the booth. Your plan is to sell each ice cream cone for $2.89. Note that in business, costs are any money you pay out. Revenue is any money you receive through sales. Profit is total revenues minus total costs. 1. Write a function, C(n), to represent your total costs for the week if you sell n ice cream cones. C(n) = 2. Revenue is the amount of money you earn from selling ice cream cones. Write a function, R(n), to represent the revenue from the sale of n ice cream cones during the week. R(n) = 3. Write a function, P(n), that represents the profits for selling n ice cream cones in a given week. P(n): 1. What is the minimum number of ice cream cones you must sell in order to not lose money?
