Question

Greg paid $33 for 2 shirts and $48 for 3 shirts, including a fixed shipping fee. Assuming the same function applies to

Answer 1

• The amount of 1 shirt before the shipping fee is $16
• If the shipping fee was increased,  b changes
• If the cost per shirt was increased, m changes

What is linear equation?

A linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form a x + b = 0

As it is given that the equation is y =mx + b

We have two coordinates as; (2,33) and (3,48)

So, we get

2m + b =33..............................(1)

3m +b = 48...............................(2)

On Solving equation (1) and(2) we get,

m= 16

As the shipping fee was increased then b changes

and if the cost per shirt was increased then m changes

The amount of 1 shirt before the shipping fee is $16

If the shipping fee was increased,  b changes.

If the cost per shirt was increased, m changes.
