How many caramel apples must you sell in order to make a positive profit?

Question

You decide to begin selling caramel apples at the local park. Your cost for each caramel apple is $1.35 plus you have to pay a fixed weekly fee of $190 for the booth. Your plan is to sell each caramel apple for $2.81. 

Write a function to represent the revenue, 

, from the sale of  caramel apples during the week.



 Write a function to represent your total costs, 

 for the week if you sell  caramel apples.

Answer 1

R(n) = 2.81n

C(n) = 190 + 1.35n

Profit = R-C = 1.46n -190

to break even 190=1.46n

n=190/1.46 = 130.14 apples

He'll need to sell 131 apples to break even or make a profit
