4.30 makeup; 40% discount; 6% tax equals

Okay, i don't want to give you the direct answer because i want you to know how to do it ... First you multuply $4.30 x .4 and you will get a number... remember  that number in your head and subtract it from the original amount of $4.30... then once you get the number from subtracting the discount, multiply that number by .6 then with that number, add the sales tax and there is your answer!

What class is this? i have no idea and i'm not going to give you the wrong answer. do you have a graph that goes with all the questions
