To find how much the debt increased in the 50-year period, we need to subtract the debt in 1971 from the debt in 2021.
Debt increased = $2.9617×10^13 - $3.98×10^11
Debt increased = $29.617×10^11 - $3.98×10^11
Debt increased = $25.637×10^11
Debt increased = $2.5637×10^12
Therefore, the debt increased by $2.5637×10^12 in the 50-year period.
To find out how much the U.S. national debt increased in the 50-year period from 1971 to 2021, you need to subtract the debt in 1971 from the debt in 2021.
The debt in 1971 was $3.98×10^11 (which is equal to $398,000,000,000).
The debt in 2021 was $2.9617×10^13 (which is equal to $29,617,000,000,000).
Now, subtract the debt in 1971 from the debt in 2021:
$2.9617×10^13 - $3.98×10^11 = $29,617,000,000,000 - $398,000,000,000
After performing the subtraction, you get:
$29,219,000,000,000
Therefore, the debt increased by $29,219,000,000,000 over the 50-year period.
So, the correct option is:
$2.9219×10^13
To find how much the debt increased in the 50-year period, subtract the debt in 1971 from the debt in 2021.
$2.9617×10^13 - $3.98×10^11 = $2.9219×10^13
Therefore, the debt increased by $2.9219×10^13 in the 50-year period.
