Answer:
Real GDP increased by 20% between 1990 and 2000
Explanation:
Real GDP (RGDP) = (Nominal GDP (NGDP) / Price level) x 100
RGDP, 1990 ($ Billion) = (360 / 120) x 100 = 300
RGDP, 2000 ($ Billion) = (450 / 125) x 100 = 360
Therefore, between 1990 and 2000, Real GDP
= (360 / 300) - 1
= 1.2 - 1
= 0.2
= 20%
Thus, the Real GDP increased by 20% between 1990 and 2000
