An economy has full-employment output of 6,000.Government purchases,G, are 1,200.Desired consumption and desired investment are:

C^d = 3600-2000r+0.10Y, and

l^d = 1200-4000r,

Where Y is output and r is real interest rate.

Suppose that the real interest rate isr=0.15. Assuming that output equals full-employment output, what is the level of desired investment in the economy? Round your answer to at least 2 decimal places.
