Answer 1

Given:

The cost of a wireless mouse is $21.99 and tax rate 4.7%.

To find:

Find the sales tax and total cost.

Explanation:

$Sales\text{ tax= Pre tax cost}\times tax\text{ rate}$$Total\text{ cost= pre tax cost + sales tax}$

Solution:

We will start with converting sales tax percentage into decimal

4.7% = 0.47

Now, to find Sales tax of wireless mouse multiply pre tax cost with tax rate.

$\begin{gathered} Sales\text{ tax = 21.99}\times0.47 \\ Sales\text{ tax=10.33} \end{gathered}$

Now, to find total cost add pre tax cost and sales tax

$\begin{gathered} Total\text{ cost = }21.99+10.33 \\ Total\text{ cost = }32.32 \end{gathered}$

Hence, these are the required values.
