To find how much the debt increased, we need to subtract the debt in 1971 from the debt in 2021.
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = $2.9617×10^13 - $3.98×10^11
Simplifying this expression gives us:
Debt increase = $2.9617×10^13 - $0.398×10^13
Subtracting the two values gives us:
Debt increase = $2.9617×10^13 - $0.0398×10^13
Combining like terms, we get:
Debt increase = $2.9219×10^13
Therefore, the debt increased by $2.9219×10^13 in the 50-year period.
The correct answer is $2.9219×10^13.
To find the increase in the national debt over a 50-year period, we need to subtract the debt in 1971 from the debt in 2021.
$2.9617×10^13 - $3.98×10^11 = $2.9219×10^13
Therefore, the national debt increased by $2.9219×10^13 (or $29.219 trillion) in the 50-year period.
To find the increase in the U.S. national debt from 1971 to 2021, we need to subtract the debt in 1971 from the debt in 2021.
Debt in 2021: $2.9617×10^13 (or $29.617 trillion)
Debt in 1971: $3.98×10^11 (or $398 billion)
Now, subtracting the debt in 1971 from the debt in 2021:
$2.9617×10^13 - $3.98×10^11 = $2.9219×10^13 (or $29.219 trillion)
Therefore, the correct answer is $2.9219×10^13 (or $29.219 trillion).
