Question

A pack of cinnamon scented pencils sell for $4.00 what is the sales tax rate if the total cost of the pencils is $4.32

Answer 1

8%

Explanation:

To get the answer we can use proportion. We know that 4$ its 100% and 4.32 its 100% + taxes.

4$ ---------- 100%

4.32 -------- x

cross multiply now

4x=4.32*100%

4x=432% /:4

x=108%

We know that 4.32 its 100% + taxes=108% so to get taxes we have to subtract 108-100.

108%-100%=8% - its the answer.

Answer 2

8%

Explanation:

$4 represents the sale price

4.32 - 4 =$ .32 represents the sale tax

Tax rate is the percentage $ .32 out of $4.

4 is 100%

.32 is x%

Cross multiply to find x, and divide by 4

x= (.32·100) / 4

x = 8

The tax rate is 8%.
