Answer 1

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.
