80/200 x/100 % 8000%/200 x x 40% 40%
x/100 * 20 = 40 x/100 = 2 x = 200%
200 x (1 - (40/100)) = 200 x 0.6 = 120 dollars.
Do it in easy stages starting with the last. A fifth of 200 is 40 A half of 40 is 20 A quarter of 20 is 5 The answer is 51/4 x 1/2 x 1/5 x 200 = 200/40 = 5
200 x 20% = 200 x 0.20 = 40
40*5=200
50 x 40 = 200
x=1

(215 x 215 x 215) = 9,938,375
There are 6 factor pairs of 200. 200 = 1 x 200 200 = 2 x 100 200 = 4 x 50 200 = 5 x 40 200 = 8 x 25 200 = 10 x 20
