Answer: (1) 120,675 
(2) 60,450
Step-by-step explanation:
(1) Nominal GDP, year 2 ($) = Sum of (Year 2 price × Year 2 quantity) 
 = 150 × 4.50 + 1,200 × 100 
 = 675 + 120,000 
 = 120,675 
 
(2) Real GDP, year 2 ($) = Sum of (Year 1 price x Year 2 quantity) 
 = 3 × 150 + 50 × 1200 
 = 450 + 60,000
 = 60,450
