Answer provided by our tutors
let
x = the cost of one hotdog
y = the cost of one hamburger
three hotdogs and two hamburgers cost 8.25:
3x + 2y = 8.25
two hot dogs and three hamburgers cost 8.00:
2x + 3y = 8.00
by solving the system of equations:
3x + 2y = 8.25
2x + 3y = 8.00
we find:
x = $1.75
y = $1.5
