Hi I need help with this questionThanks

YAS = 96 + 42P - 12Poil YAD = 1326 - 16P + 8G Suppose initially, the Poil = $83 per barrel and government spending is equal to $425. Part (a): Calculate equilibrium GDP and the price level. Part (b): Determine the magnitude of the simple multiplier if oil prices exogenously rise by $1. Part (c): Determine the magnitude of the simple multiplier if government spending exogenously increases by $1
