Question

You and a friend go to Tacos Galore for lunch. You order four soft tacos and three burritos and your total bill is $15. Your
friend's bill is $9 for two soft tacos and two burritos. How much do soft tacos cost? How much do burritos cost?

Answer 1

Using a system of equations, it is found that a soft taco costs $1 and a burrito costs $3.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

• Variable x: Cost of a soft taco.

• Variable y: Cost of a burrito.

You order four soft tacos and three burritos and your total bill is $15, hence:

$4x + 3y = 15$

Your friend's bill is $9 for two soft tacos and two burritos, hence:

$2x + 2y = 9$

$x + y = 4.5$

$y = 4.5 - x$

Hence, replacing on the first equation:

$4x + 3y = 15$

$4x + 3(4.5 - y) = 15$

$x = 1.5$

$x = 4.5 - 1.5 = 3$

Hence, a soft taco costs $1 and a burrito costs $3.
