Answer:
6 hot dogs, 2 drinks
Step-by-step explanation:
let y = number of hot dogs
let x = number of drinks
system:
y = 3x
4.5y + 2.25x = 31.50 (standard form: y = -1/2x + 7)
if you graph the system, lines intersect at (2, 6)
All the number end in a zero 10 20 30 40 50 60 70 80 90
I believe that the answer is speed in this situation but I'm not 100% sure
