To find the increase in the national debt over the 50-year period, we need to subtract the debt in 1971 from the debt in 2021:
$2.9617×10^13 - $3.98×10^11
= $2.9617×10^13 - $0.398×10^13
= $2.5637×10^13
Therefore, the national debt increased by $2.5637×10^13 or $2.5637 trillion over the 50-year period.
So, the closest answer is:
$3.0015×10^13
