From the following data, construct an expenditure schedule on a piece of graph paper. Then use the income-expenditure (45° line) diagram to determine the equilibrium level of GDP.

Now suppose investment spending rises to $260, and the price level is fixed. By how much wills equilibrium GDP increase? Derive the answer both numerically andgraphically.
