Fiber X cereal is 55% fiber. Fiber Max cereal is 70% fiber. Sheldon combines an amount of the two cereals in a single bowl of mixed cereal that is 65% fiber. If the bowl contains a total of 12 ounces of cereal, how much of the cereal, in ounces, is Fiber X?

X----------------------Max

55---------65----------70

65-55=10----------70-65=5

Write in cross direction:

x/m = 5/10

10x=5m

x=5/10m

or m = 2x

Given,

x+m=12

x+2x=12

3x=12

x=4
