Step-by-step explanation: To find the cost of one taco, we can use a system of equations. Let x be the cost of one burger and y be the cost of one taco. Then we have:
2x + 4y = 22.50 x + 3y = 14.50
Multiplying the second equation by -2, we get:
-2x - 6y = -29 2x + 4y = 22.50
Adding the two equations, we get:
-2y = -6.50 y = 3.25
So one taco costs $3.25.
