It might help you to know that a percent is the same number starting in the one-hundredths decimal column. So, 5% is .05 and 5.5% is .055. To find what 5% of something is, multiply it by .05

Also, when you have a money problem involving tax, you will need to do three steps.

FIRST, figure out what the tax is. This involves multiplying the price by the percent. For example, in the first problem it's

$19.95 x .05 = $.9975

SECOND, round the tax to the nearest money amount. Since money is only two decimal places, round to the nearest 100th. In this case the 5 rounds up the 7 to an 8, and then the 8 rounds up the 9 to 10 and the other 9 also goes to 10. So, the $.9975 rounds up to $1.00.

THIRD, add the amount of the tax to the price.

$19.95 + $1.00 = $20.95

**1.** 5% of 19.95 = 5/100 X 19.95 = .9975

therefore total cost = 19.95+.9975 = **$20.9475**

**2.** 6% of 499 = 6/100 X 499 = 29.94

therefore total cost = 499 + 29.94 = **$528.94**

**3.** 5.5% of 3500 = 5.5/100 X 3500 = 192.5

therefore total cost = **$3692.5 **

1.

19.95 x .05 = $.997

19.95 + .997 = $20.95

2.

499 x .06 = $29.94

499 + 29.94 = $528.94

3.

3500 x .055 = $198.5

3500 + 192. 5 = $3692.5

1) T-shirt,$19.95 tax rate,5%

19.95 x .05 = **$.997**

19.95 + .997 = **$20.95**

2)refrigerator,$499 tax rate,6%

499 x .06 = **$29.94**

499 + 29.94 = **$528.94**

3)motorcycle,$3,500 tax rate,5.5%

3500 x .055 = **$198.5**

3500 + 192. 5 = **$3692.5**

1) tax rate is 5% so the t-shirt new price with the tax would be 105%

T-shirt= 105/100*19.95= **$20.9475**

2) refridgerator= 106/100*499= **$528.94**

3) motorcycle= 105.5/100*3500= **$3692.50**
