You purchase 91/2 yards of fabric at $11.00 per yard. There is a 7% sales tax. What is the total cost of fabric?

9.5 * 11.00 * 1.07 = ?

$12.07

9.5x11.00=104.5

104.5x1.07=111.815
$111.82

To calculate the total cost of the fabric, we need to find:

1. The cost of the fabric before tax.
2. The amount of sales tax.
3. The total cost of the fabric, including tax.

Let's break it down step by step:

1) Cost of the fabric before tax:
The cost per yard is $11.00, and you purchased 9 1/2 yards of fabric. To find the cost before tax, multiply the cost per yard by the number of yards you purchased:
Cost before tax = $11.00/yard * 9.5 yards

To calculate this, we convert the mixed number to an improper fraction: 9 1/2 is equivalent to 19/2.
Cost before tax = $11.00/yard * 19/2 yards

Now, simplify the fraction by multiplying the numerators and the denominators:
Cost before tax = $11.00 * 19 / 2

Calculate the multiplication first:
Cost before tax = $209.00 / 2

Divide the numerator by the denominator:
Cost before tax = $104.50

So, the cost of the fabric before tax is $104.50.

2) Amount of sales tax:
The sales tax rate is 7%. To find the amount of sales tax, multiply the cost before tax by the tax rate:
Tax amount = Cost before tax * Tax rate
= $104.50 * 7/100

Calculate the multiplication first:
Tax amount = $104.50 * 0.07

Tax amount = $7.32

Therefore, the amount of sales tax is $7.32.

3) Total cost of the fabric, including tax:
To find the total cost of the fabric, add the cost before tax and the sales tax amount:
Total cost = Cost before tax + Tax amount
= $104.50 + $7.32

Calculate the addition:
Total cost = $111.82

So, the total cost of the fabric, including tax, is $111.82.
