Question

Mr. Newton wants to buy a shirt in Leavenworth Kansas that cost $20.The sales tax in Leavenworth is 8%. What would be the total price of the shirt after adding the sales tax?

Answer 1

First find the amount the price increased.

amount of change
= (percent change) x (starting value)

= (8%) x ($20)

= (0.08) x ($20)

= $1.60

(Remember to convert the percent to a decimal before multiplying.)

Now add the tax onto the price:

$20 + $1.60 = $21.60

The price, including sales tax, is $21.60.
