Question

A blu ray player costs $80.99 in the store. what would your total cost be if the sales tax is 5.5%

Answer 1

$ 85.44

Explanation:

We have the value after tax, we must calculate the sum between the original value and the value equivalent to the established percentage, therefore, we calculate it like this:

`\begin{gathered} p=80.99+80.99\cdot(5.5)/(100) \\ p=80.99+4.45 \\ p=\text{ \$85.44} \end{gathered}`

The final price is $ 85.44
