PLEASE HELP ME THIS IS DUE ON MONDAY!! 1: You go to a car dealership and want to buy a car that is $18000. What you don't know is that the car has a discount of 20% off. How much would you pay for the car with the discount?

2: you go to the store to buy a coat that normally costs $125. You have a coupon for 15% off but after the discount you have to pay 5% sales tax. How much will you end up paying for the coat?
