Given:
Amount of bill = $25
Coupon = 15% off
Tip = 20% after discount is applied.
To find:
The total that Dylan's mom will pay at the restaurant.
Solution:
We have,
Amount of bill = $25
Discount = 15%
Amount after discount = 25 - 15% of 25
[tex]=25-\dfrac{15}{100}\times 25[/tex]
[tex]=25-3.75[/tex]
[tex]=21.25[/tex]
So, amount after discount is $21.25.
Tip = 20%
Total Amount = Amount after discount + Tip
[tex]\text{Total Amount}=21.25+\dfrac{20}{100}\times 21.25[/tex]
[tex]\text{Total Amount}=21.25+4.25[/tex]
[tex]\text{Total Amount}=25.5[/tex]
Therefore, Dylan's mom will pay total $25.5 at the restaurant.
