<h3>What is Percentage?</h3>
A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
Given to us
The initial cost of the bike, P = $950
Additional coupon = 30%
Marked down = $200
We know the original cost of the bike which is $950. therefore, when the price of the bike was marked down, its cost will be,
$900 - $200 = $700
Thus, the marked-down cost of the bike will be $700.
As it is given that we have an additional 30% off after the markdown, therefore, cost of the bike will be 70% of the marked price,

Hence, the final cost of the bike will be equal to $490.
