If disposable income is $20 trillion, taxes are $6 trillion, and transfers are $4 trillion, then income is $_____ trillion. Plea

Serjik [45]

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.

$\text{Disposable income}=\text{Income}+\text{Transfers}-\text{Taxes}$

$\$20=\text{Income}+\$4-\$6$ , where each amount is in trillions.

$\$20=\text{Income}-\$2$

$\$20+\$2=\text{Income}-\$2+\$2$

$\$22=\text{Income}$

Therefore, the income is $22 trillion.
