To find the increase in the 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

Simplifying the subtraction:

= $2.5637×10^13

So, the debt increased by $2.5637×10^13 in the 50-year period.

The closest option is $2.9219×10^13.

To find how much the U.S. national debt increased over a 50-year period, we subtract the debt in 1971 from the debt in 2021.

The debt in 2021 is given as $2.9617×10^13 (29.617 trillion dollars).

The debt in 1971 is given as $3.98×10^11 (398 billion dollars).

Subtracting the debt in 1971 from the debt in 2021:

$2.9617×10^13 - $3.98×10^11 = $2.9219×10^13 (29.219 trillion dollars)

So, the U.S. national debt increased by approximately $2.9219×10^13 (29.219 trillion dollars) over the 50-year period.

Therefore, the correct answer is $2.9219×10^13.
