Question

Karen's mother get a restaurant bill for $25 . he 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 explain or show your reasoning

Answer 1

Price after discount: $21.25

Tip amount: $4.25

Explanation:

We know the following information:

Original bill: $25

Coupon: 15% off

Tip: 20% after the discount is applied.

Now, we first calculate the bill price after the discount. After a 15% discount, Karen needs to pay only 100% - 15% = 85% of the original amount and it is

`(85\%)/(100\%)*\$25=\$21.25`

Hence we know that Karen has to pay $21.25 after the coupon is applied.

Now we calculate the tip amount.

The tip amount is 20% of the discounted price; therefore,

`(20\%)/(100\%)*\$21.25=\$4.25`

Hence, we find that the tip amount is $4.25.

To conclude,

Price after discount: $21.25

Tip amount: $4.25
