Well scratch off A since $70 bills do not exist. answer C is also wrong and so is answer b and through all my calculatons answer D is the best choice in my opinion
The solution is:
.1*50+x=.25(50+x) 5+x= 12.5+ .25x
x-.25x=12.5-5 .75x=7.5 x=7.5 or .75
-2x^2 + 3x - 9 = 0
The quadratic is not factorable so quadratic formula must be used.
x = (-b + - √(b^2 - 4ac))/2a
a = -2, b = 3, c = -9
x = (-3 + - √(9 - 4*-2*-9))/-4
x = (-3 + - √(-63))/-4
x = -3 + - 3i√7
--------------
-4
x = 3 + 3i√7 x = 3 - 3i√7
------------ ------------
4 4
There is a 1/6 chance that the first one will land on 6, and there is a 1/3 chance that the second one will land on an odd #
