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.
