Idk if im doing this stuff right or not helpp please !!?

Oh Mana! Those old percentages get to all of us from time to time. Let's be sure you and I fully understand that little % sign. It comes from French meaning "pour cent" with pour meaning for and cent indicate 100 like in century. So , for what ever amount is shown, say 5% means 5 out of or for each 100., or 5/100, or 1/20 0r .05 in the decimal system.1) .04X=11.96 , X = 11.96/.04=$299 Proof: .04 x 299=11.96 2.) I don't know if you mean total discounts or stepped discounts such as 12% first,8% on balance and another 4% stacked onto final balance.: However adding up the percentages one gets 24% or 24/100=4/25=.24 . Just multiply the total by the propre percen in fraction or decimal and you will get how much the discount is. 3.) .08x 984=$78.72 commision 4.).05 x 25 x 160=$200 commision. Hope this helps. Good Luck
