Question

The sales tax is $82.50 on a stereo sound system purchase of $1650. Find the sales tax rate

Answer 1

The rate is the quotient of the tax and the total

Since the tax is $82.50

Since the total is $1650

Then divide 82.50 by 1650, then multiply by 100%

`(82.50)/(1650)*100=5`

The sales tax rate is 5%
