Question

Mark works at a shoe store where he earns a weekly salary of $200 plus 20% of his weekly sales. His goal is to earn at least $500 each week. In order to reach his goal, what is the minimum amount of sales he must achieve each week?​

Answer 1

If $1: 1500 items

If $20: 75 items

If those answers are not applicable, divide 1500 by whatever the cost of the shoes he is selling — that will be how many he will need to sell.

Explanation:

So first lets set up an equation to figure this out.

So we know that he makes 20% based off of sales, so we’ll convert this to a decimal:

20% -> .20

Next we’ll make an equation to see what is needed to get at least $500.

0.20x + 200 = 500

Next we’ll have to get x by itself.

`0.20x + 200 = 5000.20x = 300`

Next divide both sides:

`X = 1500`

So if he is making sales of $1 he will need to sell 1500 items.

If he is selling them at $20, he will need to sell 75 items.

What ever the price value is for the items, divide that from 1500.
