Consider the circuit below and solve for the following $($all opamps are ideal and have rail$-$to$-$rail output swing but they cannot drive their outputs outside of those supply rails$).(25$ points$)$

a$)$ Solve for the output voltage, Vout.

b$)$ Solve for the output current, Iout.

c$)$ If the $4\mathrm{.}5$V supply is set to zero volts, what value do you expect for Vout?
