Given

You have a coupon for 30% off your dinner.

Your total bill was $50.

You also need to pay a 7% sales tax and leave a 22% tip.

After a 30% discount the cost of the bill is;

The remaining bill is 50 - 15 = $35.

After the discount adds 7% sales tax.

The bill after sales tax is = 35 + 2.45 = $37.45.

With the discount, tip + tax included, adding 22% tip is;
