## question 1

1. c1=u-(((y*c1*V)/(K+c1))*(c2/(c2+K))/q)
2. c2=u2- (((y*c1*V)/(K+c1))*(c2/(c2+K))/q)

## question 2

the feed rate is a direct input that affects the steady states, in the equations everything else is being subtracted from the feed rate, showing that it is primarily responsible for the steady states value.

## question3

the replacement suggested in question 3 would result in the steady states decreasing in both cases considering each nutrient.
