Kiran's mother gets a restaurant bill $25. She has a coupon for 15% off . After the discount is applied, she adds 20% as a tip. What is the total after the discount and tip ?

$25.50

Step-by-step explanation:

Given :

Bill = $25

Coupon on bill = 15%

Discounted bill = (100 - 15)% * $25

Discounted bill = 0.85 * $25 = $21.25

Tip = 20% of discounted bill

Tip amount = 0.2 * 21. 25 = $4.25

Total amount = $21.25 + $4.25 = $25.50
