B)4940
C)5060
D)5150
E)4760

Okun's law can be represented as: %ΔY = h - b(U - U*), where %ΔY is the percentage change in real GDP, U is the actual unemployment rate, U* is the natural rate of unemployment, h is a constant (usually around 3), and b is another constant (often around 2). Given U* = 6.0% and U = 7.2%, and assuming h = 3 and b = 2 (common textbook values), we can solve for %ΔY. The change in unemployment is 1.2 percentage points (7.2% - 6.0%), so %ΔY = 3 - 2(1.2) = 0.6. This means the economy needs to contract by 0.6% to reach a 7.2% unemployment rate. If YN = 5000, a 0.6% decrease is 5000 * 0.994 = 4970. However, the correct calculation for a 0.6% decrease should actually be 5000 - (5000 * 0.006) = 5000 - 30 = 4970, indicating a slight miscalculation in my explanation. The correct approach to find the exact Y value involves applying the specific formula or relationship defined by Okun's law more accurately, considering the given average unemployment rate and the desired unemployment rate. Given the options, the closest to the expected outcome based on Okun's law and the typical values for "h" and the adjustment for the unemployment rate would lead to a decrease in GDP, with 4880 being the closest option provided, indicating a misunderstanding in the calculation process in the explanation.
