Question

What is the total cost of a $721 tablet computer that is on sale at 14% off if the local sales tax is 3%?

Answer 1

$638.66

Explanation:

The first thing is to determine the discount value, as follows:

`\begin{gathered} d=721-14\%(721) \\ \\ d=\:721-(14)/(100)\left(721\right)\: \\ \\ d=721-100.94 \\ \\ d=\text{ \$}620.06 \end{gathered}`

Now we apply the sales tax, like this:

`\begin{gathered} t=620.06+3\%(620.06) \\ \\ t=620.06+18.60 \\ \\ t=\text{ \$}638.66 \end{gathered}`

So the total cost of the tablet computer is $638.66
