Which system represents the problem? Click on the correct answer.
Allan wants to buy hamburgers and
french fries for a group. He has $25 to
spend. He needs to buy 10 hamburgers.
Hamburgers are $1.2 each and fries are
85 cents per order. How many orders of
french fries can he buy?
1.2x +.85y = 25; x = 10
x + y = 25; x = 10
1.2x +.85y = 10; x = 25
You can use a system of equations to find
the answer. Let x = the number of
hamburgers, and y = the number of
orders of french fries.
1.2(10x) + .85y = 25
