The linear equation that represents the total cost Josh charges for shipping is y = 0.15x.
"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."
Given, Josh charges a fee of $0.15 per ounce for shipping and handling.
We need to find out the equation that represents total cost of shipping and handling 'y' for shipping an item that weighs x ounces.
Therefore, total cost = charges per ounce × total weight of the package
⇒ y = 0.15 × x
⇒ y = 0.15x
