Answer: $18.19
step by step explanation:
first you must find the amount of money that lins father gets off on the coupon by using the equation 20•0.15=3 meaning that lin’s father gets 3 dollars off
next you find the pre-tax total which in this case would be by using the equation 20-3=17 so the pre-tax total is 17 dollars
then you find the percentage of the tax that you have to add on to the pre-tax total which would be using the equation 17•0.07 and that equals 1.19 dollars in tax
finally, you add the pre-tax total with the sales tax by adding the two (17+1.19) to get a total of 18.19 dollars or $18.18

So what I did was the terms that were alike like this: (5x -19x)+(20y+36y)+4.27xy+9.11. Then I simplified and got -14x+56y+4.27xy+9.11. The terms 4.27xy and 9.11 were not in ()'s because they were the only ones with an alike term. Hope that helps and also try to doing the steps and see what you get. If you get it wrong look to see where you messed up and try again! If I am wrong please notify me, I would appreciate it!
