a box of munchkins contains chocolate and glazed donut holes. if Gloria ate 2 chocolate , then 1/11 of the remianing munchkins would be chocolate. if she added 4 glazed to the box, 1/7 of the box would chocolate. how many munchkins are in the original box?

math - Steve, Wednesday, September 28, 2011 at 3:31pm
g = glazed holes
c = chocolate holes

c+g-2 = 11(c-2)
c+g+4 = 7c

Solve these to get
c=4
g=20

Eat 2c, leaving 2c/22 total = 1/11
Add 4g, gives 4c+24g = 4/28 choc.
