Answer:
The price for a small glass of milk is $0.95, and the price for a breakfast taco is $1.15.
Step-by-step explanation:
Let the price of a taco be x and the price for a small glass of milk be y.
![x + y = 2.1](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%202.1)
![2x + 3y = 5.15](https://tex.z-dn.net/?f=2x%20%2B%203y%20%3D%205.15)
Multiply the first equation by 2:
![2x + 2y = 4.2](https://tex.z-dn.net/?f=2x%20%2B%202y%20%3D%204.2)
Subtract the new third equation from the second equation:
![(2x + 3y) - (2x + 2y) = 5.15 - 4.2](https://tex.z-dn.net/?f=%282x%20%2B%203y%29%20-%20%282x%20%2B%202y%29%20%3D%205.15%20-%204.2)
![y = 0.95](https://tex.z-dn.net/?f=y%20%3D%200.95)
Hence, the price for a small glass of milk is $0.95.
Substitute y into the first equation.
![x + 0.95 = 2.1](https://tex.z-dn.net/?f=x%20%2B%200.95%20%3D%202.1)
![x = 1.15](https://tex.z-dn.net/?f=x%20%3D%201.15)
Therefore, the price for a breakfast taco is $1.15.
