Final answer:
The growth rate of real income from 2021 to 2022 is calculated by dividing the increase in income by the income for 2021, then multiplying by 100%. The calculated growth rate is approximately 3.11%, so the correct answer is b. 3.1 percent.
Step-by-step explanation:
To calculate the growth rate of real income over the period from 2021 to 2022, you can use the following formula:
Growth Rate = ((Real Income in 2022 - Real Income in 2021) / Real Income in 2021) x 100%
Plugging in the given values, we get:
Growth Rate = (($18,635 - $18,073) / $18,073) x 100% = (562 / 18,073) x 100% ≈ 3.11%
Therefore, the correct answer is b. 3.1 percent.
