Table 2-5 presents the price of and units of aggregate output for 199x and 199y.

(a) Present in Table 2-6, nominal GDP for 199x and 199y.

(b) Also calculate in Table 2-6 real output for 199y by measuring l99y output in l99x prices. What is the purpose of such a calculation?

(c) What is the GDP deflator in l99y?
