**Answer:**

The growth rate of the economy´s real GDP = 5.50%

The growth rate of the economy´s real GDP per capita= 3.43%

**Explanation:**

The GDP growth rate formula is:

[GDP(t)- GDP(t-1)/ GDP(t-1)]*100

t is years. We use this formula for this problem:

($42,200-$40,000)/ $40,000= 0.055*100= 5.50%

**The growth rate of the economy´s real GDP = 5.50%**

The formula of the real GDP per capita is:

Real GDP per capita = Real GDP(t)/ population(t)

Year 1:

Real GDP per capita= $40,000/100= $400

Year 2:

Real GDP per capita= $42,200/102= $413.72

To calculate the growth rate of the real GDP per capita we use the same the same formula before but now with real GDP per capita

($413.72-$400)/$400= 0.0343 = 3.43%

**The growth rate of the economy´s real GDP per capita= 3.43%**
