Question 1114162
At Barney's Takeout Service, the price of an order of french fries is one-half the price of a cheeseburger.  An order of five cheeseburgers and three servings of french fries comes to $10.40 (without tax).  What is the cost of a cheeseburger?
Equations:
f = (1/2)c
5c + 3f = 1040 cents
----------------------------
Substitue and solve for "c":
5c + (3/2)c = 1040
10c + 3c = 2080
13c = 2080
Ans: c = 160 cents = $1.60
------------
