Question

Lisa purchased a hat for $10, a purse for $20, and a book for $23. The sales tax rate was 7.2 percent. What was the total amount she paid?

Answer 1

56.81$ she paid

Explanation:

Answer 2

$56.82

Explanation:

The sum of all the stuff she bought is 10+20+23, so 53.

Now you need to find the tax, so you multiply 53 x 7.2%, and to change a % to a number you move the decimal place two to the left, so you get .072

$53 x .072 = $3.816 sales tax

$53 for the stuff plus $3.816 tax = $56.816

and since money is only two decimal places and the 6 is higher than 5, you have to round up to the nearest penny, so $56.82!
