Answer:
The answer is $210.
Step-by-step explanation:
In order to determine the final price, we have to know about percentage. When we use percentage, we are multiplying a value by a number:
x=any number in the interval from 0 to 100.
x%=
In this case, we have to do the process twice, because in the first part, we have to determine the selling price without discount and then we have to determine the selling price with discount.
The cost price is $200 and the shopkeeper wants to sell it 40% above the cost:
$200*40%

So, the selling price without discount is 280. Then the shopkeeper offers a 25% discount:
$280*25%

Finally, the sold price of the jacket, including the discount, is $210.
