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
[tex]\textup{Discount}=\$(3999-3180)=\$819[/tex]
And the rate of discount is
[tex]\textup{Rate of discount}=\dfrac{819}{3999}\times100\%=20.48\%[/tex]
Thus, the required discount is $819 and the rate of discount is 20.48%.
Answer:819,20.48 %
Step-by-step explanation:
Initial price=3999
Final price=3180
Discount is given by
=initial price - Final price
=3999-3180=819
Rate of interest is given by [tex]\frac{initial -final }{initial }[/tex]
=[tex]\frac{3999-3180}{3999}=0.2048[/tex]
i.e. [tex]20.48 \% [/tex]
