Answer provided by our tutors
let
x = the cost of one hot dog
y = the cost of one hamburger
five hot dogs and two hamburgers cost $12.00:
5x + 2y = 12
two hot dogs and five hamburgers cost $14.25:
2x + 5y = 14.25
by solving the system of equations:
5x + 2y = 12
2x + 5y = 14.25
we find:
x = $1.5
y = $2.25
