Answer:
c) $22 trillion.
Step-by-step explanation:
We have been given that disposable income is $20 trillion, taxes are $6 trillion, and transfers are $4 trillion. We are asked to find income in trillions.
[tex]\text{Disposable income}=\text{Income}+\text{Transfers}-\text{Taxes}[/tex]
[tex]\$20=\text{Income}+\$4-\$6[/tex], where each amount is in trillions.
[tex]\$20=\text{Income}-\$2[/tex]
[tex]\$20+\$2=\text{Income}-\$2+\$2[/tex]
[tex]\$22=\text{Income}[/tex]
Therefore, the income is $22 trillion.
