At a restaurant the cost for a breakfast taco and a small glass of milk is $2.10. The cost for
2 tacos and 3 small glasses of milk is $5.15. How much does a taco cost? How much does a
small glass of milk cost?

x = taco

y = milk

x + y = 2.10$

x = 2.10 - y

2x + 3y = 5.15$

2(2.10 - y) + 3y = 5.15$

4.20 - 2y + 3y = 5.15

y = 0.95

2x + 3(0.95) = 5.15

2x = 5.15 - 2.85

x = 1.15

So one taco is 1.15$ and a small glass of milk is

0.95$
