To find how much the debt increased in the 50-year period, we subtract the debt in 1971 from the debt in 2021.
2021 debt - 1971 debt = $2.9617×1013 - $3.98×1011
= $2.9617×1013 - $0.398×1013
= $2.5637×1013
Therefore, the debt increased by $2.5637×1013 or $2.9219×1013. So the correct answer is:
$2.9219×1013
The U.S. national debt was $2.9617×1013 in 2021 and $3.98×1011 in 1971. Find how much the debt increased in the 50-year period. (1 point)
