The data below represents the price level, the aggregate demand, and the aggregate supply data for an economy.Use the data points to plot an aggregate demand curve and aggregate supplycurve for this economy.

Each curve is labeled asAS(Aggregate Supply)orAD(Aggregate Demand) and each point is labeled asa,b, orcfrom the table headings.

(Hint: Note that pointafrom theADcurve is already plotted with the correct coordinates. Plot the remaining points.)

	a	b	c
Price Level	90	130	160
Aggregate Supply (AS)	$60	$220	$340
Aggregate Demand (AD)	$320	$240	$180
