Question

A roll of plastic electrical tape costs 2.79$. If the sales tax rate is 5% then how much sales tax is being charged?

Answer 1

14¢

Explanation:

To solve this problem, we need to multiply 2.79 by 5%.

First, lets change 5% into a decimal as shown below:

5% ->
`(5)/(100)` -> 0.05

Now, lets multiply 2.79 by 0.05:

`x=2.79(0.05)`

`x=.1395`

The last step is to round our number. 0.1395 rounded to the nearest hundredth gives us .14 (14¢)

The sales tax being charged is 14¢

Answer 2

$0.1395

Explanation:

$2.79 x 0.05 = 0.1395
