Janice must account for inflation in the overall value of 2018 GDP.
In general, real GDP is calculated by dividing gdp by the Deflator (R). For example, if prices in an economy have risen by 1% since the baseline year, the deflated number is 1.01. If nominal GDP is $1 billion, then real GDP equals $1,000,000 / 1.01 = $990,099.
The factors of production needed to create output, products and services acquired by the ultimate consumers, and the sum of all exports plus imports are the final goods or services used to compute GDP.
real GDP is an inflation-adjusted measure of a country's gross domestic output.
