Question

what is the total cost of a $716 tablet computer that is on sale at 15% off if the local sales tax rate is 7%, the cost of the tablet is how much money round to two decimal places as needed

Answer 1

Since the cost of the tablet is $716

Since the discount on it is 15%

Then let us find the cost after the discount

Multiply 15% by 716 to find the amount of the discount, then subtract it from the cost

`\begin{gathered} d=(15)/(100)*716 \\ d=107.4 \end{gathered}`

Now, find the cost after the discount

`\begin{gathered} C=716-107.4 \\ C=608.6 \end{gathered}`

Let us find the cost after adding 7% for tax

The cost after the tax will be 100% + 7% = 107%

Then multiply 107% by $608.6 to find the final cost

`\begin{gathered} FC=(107)/(100)*608.6 \\ FC=651.202 \end{gathered}`

Round it to 2 decimal places, then

FC = $651.20

The final cost of the tablet is $651.20
