Answer:
A. (4, 12)
Step-by-step explanation:
Adding the second equation to twice the first will eliminate y.
2(10x +2y) +(3x -4y) = 2(64) +(-36)
23x = 92 . . . . . . . . simplify
x = 4 . . . . . . . . . divide by 23
This value matches choice A: (4, 12).
The system of equations is:
2x+1.5y=20
x+y=12
When you solve it you get:
x=4 hamburger bun packages
y=8 hot dog bun packages
