Problema Solution

Answer provided by our tutors
let
x = the price of a burger
y = the price of a drink
Chu paid 225 pesos for 3 burgers and 2 drinks
3*x + 2*y = 225
Tria paid 140 pesos for 2 burgers and a drink
2*x + y = 140
By solving the system of equations
3*x + 2*y = 225
2*x + y = 140
we find
x = 55 pesos
y = 30 pesos
the burger is 55 pesos and the drink is 30 pesos.
