Answer:
B) $1,025
Step-by-step explanation:
Gross domestic product is the total output produced by an economy within a given period which is usually a year.
Real GDP calculates the GDP without the effects of inflation.
To calculate real GDP, a base year price is used.
In this question, the base year prices would be the 2015 prices.
GDP in 2015 = (70 × $5) + (40 × $12) = $830
Real GDP in 2016 = (85 × $5) + (50 × 12) = $1,025.
Real GDP grew by : $1025 - $830 = $195
