A salesperson at a clothing store earns a 5% commission on all sales. How much commission does the sale person earn on a 300$ sale?

Multiply .05 times 300

To calculate the commission earned by the salesperson, you need to multiply the sale amount by the commission rate. In this case, the salesperson earns a 5% commission on all sales, which means the commission rate is 0.05 (5% expressed as a decimal).

The formula to calculate the commission is:
Commission = Sale Amount * Commission Rate

Now let's plug in the values given in the question:
Sale Amount = $300
Commission Rate = 0.05

Commission = $300 * 0.05

Calculating the commission:
Commission = $15

Therefore, the salesperson earns a commission of $15 on a $300 sale.
