Answer:

2t + 3m = 5.15

Explanation:

Since the problem tells us that the cost of a breakfast taco and a small glass of milk is $2.10, we can write the equation

t + m = 2.10

Since the cost of two tacos and 3 small glasses of milk is $5.15, we can write the equation

2t + 3m = 5.15

Hope this helps. :)

Answer:

The price for a small glass of milk is $0.95, and the price for a breakfast taco is $1.15.

Explanation:

Let the price of a taco be x and the price for a small glass of milk be y.


x + y = 2.1


2x + 3y = 5.15

Multiply the first equation by 2:


2x + 2y = 4.2

Subtract the new third equation from the second equation:


(2x + 3y) - (2x + 2y) = 5.15 - 4.2


y = 0.95

Hence, the price for a small glass of milk is $0.95.

Substitute y into the first equation.


x + 0.95 = 2.1


x = 1.15

Therefore, the price for a breakfast taco is $1.15.

Hope this helped!
