Question

Carter and Stetson go lunch at yummy tac. Carter orders 2 enchiladas and 3 tacos and spends $13.75 (before tax). Stetson orders 4 enchiladas and 2 tacos and spends (before tax(. What was the cost of an enchilada? What was the cost of a taco?

Answer 1

This problem requires you to use systems of equations.

x is enchiladas

y is tacos

Carter’s equation 2x+3y=13.75

Stetson equation 4x+2y=18.50

You have 3 options on solving systems of equations: graphing, substitution or elimination. I prefer substitution which means to isolate one variable in one of the equations and then plugging that variable into the corresponding variable in the other problem. Once you solve and have x= or y= plug that coefficient into the one of the equations and solve. Hope this makes sense! Please reach out if you have more questions.
