Question

Antonia buys 0.75 yard of fabric at $12.00 per yard. If she pays 5% sales tax,what is the total cost of the fabric?

Answer 1

$ 9.45

Explanation:

Antonia buys 0.75 yard of fabric at $12.00 per yard.

Price of 1 yard=$12

Price of 0.75 yard=$ (0.75×12)

= $ 9

She pays 5% sales tax

That means she has to pay 105% of $9

=
`(105)/(100)* 9`

= $ 9.45

Answer 2

$9.45

Explanation:

Given : Antonia buys 0.75 yard of fabric at $12.00 per yard.

To Find: If she pays 5% sales tax,what is the total cost of the fabric?

Solution:

Cost of fabric of 1 yard = $12.00

Cost of fabric of 0.75 yards =
`12 * 0.75`

=
`9`

She pays 5% sales tax i.e.
`5\% *9`

`(5)/(100) *9`

`0.05 *9`

`0.45`

Amount of sales tax = $0.45

Thus the total cost of the fabric = $9+$0.45 =$9.45

Hence the total cost of the fabric if she pays 5% sales tax is $9.45
