The equation describing equilibrium real GDP for a four-sector economy is given by: ye = kx[Co - cTo + Go + lo + Xol where k is the relevant multiplier. Which of the following is the correct form for k? O (a) k = 1/(1-[c(1-t)-m)]) O (b) k = 1/(1-[c(1-t)+m)]) O (c) k = 1/(1-[(c+m) (1-t)-m)]) O (d) k = 1/(1-[c(1+t)-m)]) O (e) None of the above
