Question

What is the total cost of a $717 tablet computer that is on sale at 12% off of the local sales tax rate is 7%? The cost of the tablet is ? (Round to two decimal places as needed)

Answer 1

Given: The cost of a table as

`\begin{gathered} Cost=717 \\ Discount=12\% \\ Sales-tax=7\% \end{gathered}`

To Determine: The cost of the tablet

Solution

Let us first determine the discount

`\begin{gathered} Discount=12\%*717 \\ =0.12*717 \\ =86.04 \end{gathered}`

Then calculate the discounted price

`Discount-price=717-86.04=630.96`

We would also calculate the sales tax

`\begin{gathered} sales-tax=7\%* discount-price \\ =0.07*630.96 \\ =37.86 \end{gathered}`

The total price of the tablet would be

`\begin{gathered} Total-cost=discount-price+sales-tax \\ =630.96+37.86 \\ =668.82 \end{gathered}`

Hence, the cost of the tablet is $668.82
