20% of (72 / 96) = 0.15
80 + 20% = 96
96 + 20% = 96 x (1 + (20/100)) = 96 x 1.2 = 115.2

76.80
That would be 0.2 X 96 == 19.2 ... OR $19.20
20 questions = 100% 19.2 questions = 96% its impossible to get 96% on a 20 question test. If you don't get 100%, then the best you can get is 95%.
Subtracting 20 percent from 120 gives 120 x (1 - (20/100)) = 120 x 0.8 = 96
It is 1 pound 59.2 pence.
It's just multiplication. 70 percent of your total will be 85 20 percent of your total will be 75 10 percent of your total will be 96 (85 x 0.70) + (75 x 0.25) + (96 x 0.10) = YOUR GRADE AVERAGE
15 percent of 96 percent = 0.15 x 96 percent = 14.4 percent
