Question

A home theater system is marked down from $3999 to $3180. What is the discount, and what is the rate of discount? (Round to the nearest 0.1%)

Answer 1

Answer:819,20.48 %

Explanation:

Initial price=3999

Final price=3180

Discount is given by

=initial price - Final price

=3999-3180=819

Rate of interest is given by
`(initial -final )/(initial )`

=
`(3999-3180)/(3999)=0.2048`

i.e.
`20.48 \%`

Answer 2

Answer: The required discount is $819 and the rate of discount is 20.48%.

Step-by-step explanation: Given that a home theater system is marked down from $3999 to $3180.

We are to find the discount and the rate of discount.

The discount will be given by actual price minus the marked price.

We have

Actual price = $ 3999 and marked price = $3180.

So, the discount is given by

`\textup{Discount}=\$(3999-3180)=\$819`

And the rate of discount is

`\textup{Rate of discount}=(819)/(3999)*100\%=20.48\%`

Thus, the required discount is $819 and the rate of discount is 20.48%.
