1) A sales tax of 6% of the cost of a car was added to the purchase price of $29,500.

a. how much was the sales tax? **multiply 29500 x 0.06**

b. What is the total cost of the car, including sales tax? **add 29500 + the answer to 1a above**

2) During the packaging process for oranges, spoiled oranges are described by an inspector. In one day an inspector found that 4.8% of the 20,000 pounds of oranges inspected were spoiled.

a. How many pounds of oranges were spoiled? **multiply 20000 x 0.048**

b. How many pounds of oranges were not spoiled? **subtract the answer you got for 2a above from 20000
**

Remember some things:

1. A percent is expressed as a decimal by moving the decimal point two places to the left. Examples:

5.5% - 0.055

8% = 0.08

25% = .25

2. The word "of" in a problem generally indicates that multiplication needs to take place.
