Question

5. Nick went to grocery store and spent a total of$54.93. The cashier added a 15% tax to hispurchase. How much was the tax?

Answer 1

Given:

The amount that is spent by Nickel is $54.93.

Tax on purchase is 15%

To find the tax amount:

Let x be the amount of purchase.

So, we have

`\begin{gathered} (100+15)\text{ \% }x=54.93 \\ (115)/(100)* x=54.93 \\ x=47.77 \end{gathered}`

So, the amount of purchase is $47.77.

Hence, the tax amount is

`54.93-47.77=\text{ \$}7.16`

Therefore, the tax value is $7.16.
