Answer:
The soda costs $0.75.
Explanation:
We are given that Ms. Hogan paid $13.25 for 5 tacos and one soda. We are also given that one taco costs $2.50. Therefore, we can set up a system of equations to solve for how much a soda costs.

This is our required system of equations. We are given that one taco costs $2.50, so this is our x. Therefore, the price of one soda is y.
We can use the second equation and substitute it in place of the x in the first equation to solve for the price of the soda.

Therefore, one soda costs $0.75.
