The tip amount to be given is $ 27.13
The discounted amount is $ 20.3475
Total for the bill with the discount and tip included is $ 142.4325
<em><u>Solution:</u></em>
Given that,
Sabella & her family went to Red Lobster
Their bill was $135.65
<em><u>They wanted to leave a 20% tip on the original bill amount</u></em>
Thus the tip paid is given as:
Tip amount = 20 % of 135.65
![Tip\ amount = 20 \% \times 135.65\\\\Tip\ amount = \frac{20}{100} \times 135.65\\\\Tip\ amount = 0.2 \times 135.65\\\\Tip\ amount = 27.13](https://tex.z-dn.net/?f=Tip%5C%20amount%20%3D%2020%20%5C%25%20%5Ctimes%20135.65%5C%5C%5C%5CTip%5C%20amount%20%3D%20%5Cfrac%7B20%7D%7B100%7D%20%5Ctimes%20135.65%5C%5C%5C%5CTip%5C%20amount%20%3D%200.2%20%5Ctimes%20135.65%5C%5C%5C%5CTip%5C%20amount%20%3D%2027.13)
Thus the tip amount to be given is $ 27.13
<em><u>They had a 15% off coupon on meals more than $75</u></em>
Thus the discounted amount is given as:
![Discounted amount = 15 \% of\ 135.65\\\\Discounted\ amount = 15 \% \times 135.65\\\\Discounted\ amount = \frac{15}{100} \times 135.65\\\\Discounted\ amount = 0.15 \times 135.65\\\\Discounted\ amount = 20.3475](https://tex.z-dn.net/?f=Discounted%20amount%20%3D%2015%20%5C%25%20of%5C%20135.65%5C%5C%5C%5CDiscounted%5C%20amount%20%3D%2015%20%5C%25%20%5Ctimes%20135.65%5C%5C%5C%5CDiscounted%5C%20amount%20%3D%20%5Cfrac%7B15%7D%7B100%7D%20%5Ctimes%20135.65%5C%5C%5C%5CDiscounted%5C%20amount%20%3D%200.15%20%5Ctimes%20135.65%5C%5C%5C%5CDiscounted%5C%20amount%20%3D%2020.3475)
Thus the discounted amount is $ 20.3475
<em><u>What would be their total for the bill with the discount and tip included</u></em>
Total bill = (original bill - discounted amount) + tip amount
Total bill = (135.65 - 20.3475) + 27.13
Total bill = 142.4325
Thus total for the bill with the discount and tip included is $ 142.4325
