This question involves algebraically solving the system of two equations given by the \(A D\) and \(A S\) curves. The equations for the curves are given by

a. Explain the various terms in the \(A D\) curve. Explain why \(G\) enters positively.

b. What is the value of the simple multiplier? (Hint: Refer back to the caption of Figure 23 -3.)

c. Explain the various terms in the \(A S\) curve. Explain why the price of oil enters negatively.

d. Solve for the equilibrium value of real GDP and the price level.

e. Using your solution to part (d), what is the effect of a change in \(G\) on equilibrium \(Y\) and \(P\) ? Explain.

f. Using your solution to part (d), what is the effect of a change in \(\mathrm{P}_{\mathrm{OIL}}\) on equilibrium \(Y\) and \(P\) ? Explain.

AD: YAD AS: YAS = 710 - 30P + 5G 10+5P-2Pon.
