Answer 3

To find the increase in the national debt over the 50-year period, subtract the 1971 debt from the 2021 debt:

$2.9617 × 10^13 - $3.98 × 10^11 = $2.9617 × 10^13 - $0.398 × 10^13 = $2.5637 × 10^13

So the debt increased by $2.5637 x 10^13 over the 50-year period.

The correct answer is D. $2.5637 x 10^13.

Answer 4

I apologize for the mistake. Let's calculate the increase in the national debt again:

2021 debt: $2.9617 × 10^13
1971 debt: $3.98 × 10^11

To find the increase, subtract the 1971 debt from the 2021 debt:

($2.9617 × 10^13) - ($3.98 × 10^11) = $2.9617 × 10^13 - $0.398 × 10^13 = $2.5637 × 10^13

So the debt increased by $2.5637 x 10^13 over the 50-year period.

The correct answer is D. $2.5637 x 10^13.

Answer 5

Apologies for the continued mistake. Let's calculate the increase in the national debt again:

2021 debt: $2.9617 × 10^13
1971 debt: $3.98 × 10^11

To find the increase, subtract the 1971 debt from the 2021 debt:

($2.9617 × 10^13) - ($3.98 × 10^11) = $2.9617 × 10^13 - $0.398 × 10^13 = $2.9219 × 10^13

So the debt increased by $2.9219 x 10^13 over the 50-year period.

The correct answer is D. $2.9219 x 10^13.
