Question 1009377: Students at Hammond middle school are raising money for the end of the year school party. They decide to sell for Valentine's Day. The students can buy the roses for $0.50 each from a wholesaler. They also need $60 to buy ribbon and paper to protect roses as well as materials for advertising the sale. They sell for $1.30.
a. What is the students profit If they sell 50 roses? 100 roses? 200 roses?

Profit= Revenue-(variable+fixed expenses). In your problem, you have a vaiable expense of 0.50, it is variable because if you buy 1 rose it's 0.50 and if you buy 100 it's 50. And you have a fixed expense of 60. You have to pay the 60 whether you sell 1 rose or 500.
------------------------------------------
Let's call the profit P and the number of roses they sell x:
P= 1.30x-(0.50x+60) Now substitute x with your numbers and do the math. I'll do one for an example, I'll do 100:
----------------------------------------
P= 1.30x-(0.50x+60)
P= 1.30(100)- (0.50(100)+60)
P= 130-(50+60)
P= 130-110
P= 20 is how much they made selling 100 roses.
(hint: if you only sell 50 roses you don't make any money, in fact you lose $20)
