# Sales Tax and Commission:

Formula: Sales tax= tax rate x purchase price

Example                                                                                                                                1. I went to the store and bought a new phone for \$650 and the sales tax rate is 3%. What is the sales tax?                                                                                                      1.change the sales tax rate into a decimal                                                                            3%= 0.03

2. Then multiply the price of the phone by 0.03                                                              0.03 x 650= 19.50

# Figure it out:

1. The price of a bicycle you plan to buy is \$300. The sales tax rate is 4%. How much is the sales tax?

Formula= tax rate x purchase price

# Commission

Commission- a percent of the amount of your sales

To find the commission you use the same formula.

Formula- Commission= sales x commission rate

EXAMPLE:

1. You go and buy a computer for \$800 and a worker helped you. The worker's commission rate is 5%. How much commission do they get?

So you first have to change the commission rate to a decimal.                                            5%=0.05                                                                                                                                 Then you multiply the commission rate by the sales

0.05 x 800=\$40

so the worker's commission is \$40.

# Examples:

1. Find the commission on a \$100 sale with a commission rate of 10%.

Formula= Commission=sales x commission rate
