A pair of jeans = $40.00
There is a 6.5% sales tax.
First change the % into a decimal by moving the decimal point two spaces to the left.
0.065
Multiply that by 40.00 to find out how much the tax is.
40 × 0.065 = 2.6
Now add the tax to the initial price.
40.00 + 2.6 = 42.60
The total cost is $42.60.
The algebraic expression is: x% * 100
