Question 1128177: I need to solve this question by creating a system of equations but I can't figure out how to set it up:
The parent-teacher organization is selling baskets of cookies for a school fundraiser. The materials needed to make each basket cost $3.75, and the baskets are being sold for $10 each. If they spend $75 to advertise their sale, how many baskets must be sold to break even?
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
b=baskets
3.75 b= cost
10b=revenue
cost=75+3.75b
must equal 10b to break even
6.25b=75
b=12 baskets
check Revenue is $120 for 12
12 baskets cost $45 and $75 for advertising, $120 is cost.
