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:
Simplifying by 7:
Mary sold 14 small boxes of tangerines and 3 large boxes of tangerines for a total of $182, hence:
Since :
Then
A small box of tangerines costs $10 and a large box costs $14.
