<h2>Linear system</h2>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
A group of friends bought 5 containers of popcorn and 4 granola bars at the movie theatre for $42.50.
The next week, the same group of friends bought 3 containers of popcorn and 6 granola bars for $34.50.
<h3>To find </h3>
The equation and solution of the equation.
<h3>How to get it?</h3>
Let p represent the cost of one container of popcorn.
Let g represent the cost of one granola bar.
A group of friends bought 5 containers of popcorn and 4 granola bars at the movie theatre for $42.50.
5p + 4g = 42.50 .....1
The next week, the same group of friends bought 3 containers of popcorn and 6 granola bars for $34.50.
3p + 6g = 34.50 .....2
From Equations 1 and 2, we have
p = 6.5 and g = 2.5
Thus, the cost of one container of popcorn and granola is $6.5 and $2.5.
