i have three components in a stream I am feeding into a separator. The stream has twice as much of component B as it does component A$,$ on a mass basis. The stream has three times as much of component C as it does component A$,$ on a mass basis. The stream produces two streams, an Outlet and a Waste stream. The outlet stream has $(1)/(2)$ of the component A that was fed to the separator, and the outlet stream has a mass fraction of $0\mathrm{.}25$ A$.$ The outlet stream also has no B in it and a total flow rate of $20$ pounds per minute. Find the mass flowrate of the feed stream and the mass fractions $($all three components$)$ and total flowrate of the Waste stream
