45 time 60 = 2700
One box is 20$ and 20 boxes is 400$
If this is probability then the answer should be $.50 bacause you throw the dart until you hit 1 balloon there is 100 white balloons so there is a .75% chance to hit white, a .02% chance to hit red and a .22% chance to hit green. the most likely one to hit is white. so you would earn
$.50 per game
