Answer:
a. nominal GDP is $1800, real GDP is $2000, and the GDP deflator is 90
Step-by-step explanation:
Gross domestic product is the sum of all final goods and services produced in an economy within a given period which is usually a year..
Nominal GDP is GDP calculated using current year prices.
Real GDP is GDP calculated using base year prices.
Nominal GDP = (50 × $20) + (100 × $8)
= $1800
Real GDP = (50 × $10) + (100 x $15) = $2000
GDP =( nominal GDP/ real GDP) × 100
($1800/$2000) x 100 = 90
