SALLY BOUGHT 3 HAMBURGERS AND 2 DRINKS FOR $10.45. JASON BOUGHT 4 HAMBURGERS AND 3 DRINKS FOR $14.30. HOW MUCH WOULD 1 HAMBURGER AND 1 DRINK COST?
Answer provided by our tutors
Let
x = the cost of one hamburger
y = the cost of one drink
3 hamburgers and 2 drinks altogether cost $10.45:
3x + 2y = 10.45
4 hamburgers and 3 drinks altogether cost 14.30:
4x + 3y = 14.30
We have the following system of equations:
3x + 2y = 10.45
4x + 3y = 14.30
