Question

a. 18.0 percent
b. 2.5 percent
c. 5.62 percent
d. 18.6 percent
e. 3.1 percent

Answer 1

To calculate the growth rate of real income from 2018 to 2019, we can use the formula for growth rate:

\[
\text{Growth Rate} = \frac{\text{Value in 2019} - \text{Value in 2018}}{\text{Value in 2018}} \times 100
\]

Plugging in the values:

\[
\text{Growth Rate} = \frac{18,635 - 18,073}{18,073} \times 100
\]

Calculating the difference:

\[
18,635 - 18,073 = 562
\]

Now, replace the difference in the formula:

\[
\text{Growth Rate} = \frac{562}{18,073} \times 100
\]

Calculating the fraction:

\[
\frac{562}{18,073} \approx 0.0311
\]

Now converting it to a percentage:

\[
0.0311 \times 100 \approx 3.11\%
\]

Thus, the growth rate of real income from 2018 to 2019 is approximately 3.1 percent.

The correct answer is **e. 3.1 percent**.
