someone could help thank you:-)

1. Aggregate demand, aggregate supply, and the Phillips curve
In the year 2023, aggregate demand and aggregate supply in the fictional country of Drooble are
represented by the curves AD202and AS on the following graph. The price level is 102. The graph
also shows two possible outcomes for 2024. The first potential aggregate demand curve is given by
the ADA curve, resulting in the outcome illustrated by point A. The second potential aggregate
demand curve is given by the ADB curve, resulting in the outcome illustrated by point B.

OUTPUT (Trillions of dollars)
Suppose the unemployment rate is 5% under one of these two outcomes and 2% under the other.
Based on the previous graph, you would expect

2023 and 2024 is
Based on your answers to the previous questions, on the following graph use the purple point
(diamond symbol) to plot the unemployment rate and inflation rate if the economy is at point A.
Next, use the green point (triangle symbol) to plot the unemployment rate and inflation rate if the
economy is at point B. (As you place these points, dashed drop lines will automatically extend to
both axes.) Finally, use the black line (cross symbol) to draw the short-run Phillips curve for this
economy in 2024.
Note: For graphing pruposes, round the inflation rate under each outcome to the nearest whole
percent. For example, round 1.9% to 2.0%.
Hint: Hover your cursor over each point after you plot it to make sure you have placed it on the
exact coordinate you intended.
