: I needed help with setting up the eqations for this problem:
27. A bread maker costs $199. The ingredients and electricity to make one loaf of bread with the machine cost $.79. A loaf of bread of similar quality costs $1.59 at a grocery store.
a.)write two equations giving the total cost "C" in terms of the number of loavs "l" made or purchased for each situation.
b.) Solve the system of equations to find the number of loaves of bread you have to make before the breadmakerpays for itself. This question is from textbook algebra 2 explorations and applycations

Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
Let L = number of loaves of bread.
C = total cost of the loaves.
Machine cost:
C = 199 + .79L

Store cost:
C = 1.59L

199 +.79L = 1.59L

Subtract .79L from each side:
199+.79L -.79L = 1.59L - .79L
199=.8L

Divide both sides by .8:

Answer: On the 160th loaf of bread, the machine becomes the lesser cost.
