Final answer:
To find the price of each taco and each quesadilla, set up a system of equations and solve for the prices.
Step-by-step explanation:
To find the price of each taco and each quesadilla, we can set up a system of equations. Let's say the price of a taco is 'x' and the price of a quesadilla is 'y'. From the given information, we have two equations:
60x + 50y = 427.50
90x + 60y = 562.50
To solve this system of equations, we can use the method of substitution or elimination. Solving this system, we find that the price of each taco is $3.50 and the price of each quesadilla is $4.50 (option a).
