Using a system of equations, it is found that a small box of tangerines costs $10 and a large box costs $14.

<h3>What is a system of equations?</h3>
  • 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 <em>variables </em>are:

  • Variable x: Cost of a small box.
  • Variable y: Cost of a large box.

Krystal sold 7 small boxes of tangerines and 14 large boxes of tangerines for a total of $266, hence:

7x + 14y = 266

Simplifying by 7:

x + 2y = 38

x = 38 - 2y

Mary sold 14 small boxes of tangerines and 3 large boxes of tangerines for a total of $182, hence:

14x + 3y = 182

Since x = 38 - 2y:

14(38 - 2y) + 3y = 182

25y = 350

y = \frac{350}{25}

y = 14

Then

x = 38 - 2y = 38 - 2(14) = 10

A small box of tangerines costs $10 and a large box costs $14.
