Step-by-step explanation:
The computation is shown below:
a. Nominal GDP
For the year 2003
= $3 × 500,000 + $500 × 3,000 + $25 × $1,000
= $1,500,000 + $1,500,000 + $25,000
= $3,025,000
For the year 2004
= $4 × 600,000 + $600 × 4,000 + $30 × 1,500
= $2,400,000 + $2,400,000 + $45,000
= $4,845,000
b. Real GDP
For the year 2003
= Nominal GDP of the year 2003
= $3,025,000
For the year 2004
= $3 × 600,000 + $500 × 4,000 + $25 × 1,500
= $1,800,000 + $2,000,000 + $37,500
= $3,837,500
c. The implicit price deflator is
= Nominal GDP for 2004 ÷ Real GDP for the year 2004
= $4,845,000 ÷ $3,837,500
= 1.26
d. The rate of inflation is
= (GDP deflator - 1) × 100
= (1.26 - 1) × 100
= 26%
