Question

At Freddy's Eatery, three steak burgers and two orders of fries cost $18. Two steak

burgers and three orders of fries cost $15.75. What is the cost of one steak burger?
A) $5
B) $4.50
D) $6.50
C)
$2.25

Answer 1

To solve this problem, we can set up a system of equations to represent the given information. Let x represent the cost of one steak burger. Then we can set up the following system of equations:

3x + 2(f) = 18

2x + 3(f) = 15.75

Where f represents the cost of one order of fries.

Subtracting the second equation from the first equation gives us:

x = 18 - 2(f) - 15.75 + 3(f)

= 18 - 15.75

= 2.25

Therefore, the cost of one steak burger is $2.25, which is answer choice C.
