Total number of non-jelly candies = 3*3*2*2 = 36.
Total number of jelly candies = 3*2 = 6.
Their proportion = 36/6 = 6/1.
3.
Let x be amount that "regular" ballerina loses per hour. Then
7*8*x = 20
7*4*x + y*4*x/2 = 20.
We need to find "y". Since right parts of both equations are equal,
7*8 = 7*4 + y*4/2
which gives
y = 14.
