Question from kathie, a parent:

find the profit income is $\$500$ expenses $\$120$

Hi Kathie,

If you spent $\$120$ to make an item and you sold it for $\$500$ then you have made $\$500 - \$120 = \$380.$ This is your profit.

Many times you want to express your profit as a percentage of the selling price. To do this first express the profit as a fraction of the selling price. The profit is $\large \frac{380}{500}$ of the selling price. To convert this to a percentage multiply by 100.

I hope this helps,
