lara [203]

We can write the first part of this problem as: What is 6.5% of $29,990.

"Percent" or "%" means "per 100" or "out of 100". Therefore

6.5 hope this helps (:

%

can be written as

6.5

100

.

When dealing with percentages the word "of" means the product of or to multiply.

Let's call the sales tax amount we are looking for

s

.

We can now write the problem as:

s

=

6.5

100

×

$

29990

s

=

$

194935

100

s

=

$

1949.35

The sales tax on the car is: $1,949.35.

The total price of the car is then:

$

29

,

990.00

+

$

1

,

949.35
