The local garden store sells bags of mulch for $4.98 each and will deliver the bags for a fee of $15 if Amber purchases 15 bags and has them delivered what is the total amount that Amber will pay?

$89.70

Step-by-step explanation:

To solve this equation, let's formulate a linear equation.

Let equal bags of mulch.

Let equal the total amount.

We know the price of each bag of mulch ($4.98), so we can represent this as:

We also know that there's a fee of $15, so we can just represent this as:

Let's put these values into an equation:

Now with an equation, we know that she purchases a total of 15 bags, so let's substitute for :

Multiply:

Add:

_

Check your work by substituting the total amount into the initial equation:

Subtract from both sides of the equation:

Divide both sides of the equation by the coefficient of , which is :

Amber did in fact purchase 15 bags, so we know our total amount is correct!
