If the sales tax rate in Perryville

TEA [102]

To find the tax rate (in this case, 8%), you must multiply the base cost ($128) by the percentage (or, divide the cost by 100 and multiply that by the percentage).

$128÷100=$1.28

$1.28×8%=$10.24

So, the amount of tax that is charged on the table is exactly $10.24.

Hope this helps!

Katie has read 34% of a book. If she read 85 pages, does she have more than or fewer than 125 pages left to read? Explain

mestny [16]

Determine the percent of book she hasn't read.
percent = 100% - percent she has read
percent = 100% - 34%
percent = 66%
She hasn't read 66% of the book.

Find the amount of page she hasn't read.
page = $\dfrac{\text{percent hasn't read}}{\text{percent has read}} \times\ \text{page has read}$
page = $\dfrac{66\%}{34\%} \times\ 85$
page = $\dfrac{66}{34} \times\ 85$
page = $\dfrac{5,610}{85}$
page = 165

The number of page she hasn't read is 165. It's more than 125.
