the u.s. national debt was $2.9617 x 10^13 in 2021 and $3.98 x 10^11 in 1971. find out how much debt increased in the 50- year period

Answer 1

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

Increase = $2.9617 x 10^13 - $3.98 x 10^11

Now, we need to convert the debt values into the same form. Let's convert $2.9617 x 10^13 into the same format as $3.98 x 10^11:

$2.9617 x 10^13 = $29.617 x 10^12

Now, substitute the values:

Increase = $29.617 x 10^12 - $3.98 x 10^11

= $29.617 x 10^12 - $0.398 x 10^12

= $29.219 x 10^12

Therefore, the debt increased by $29.219 x 10^12 over the 50-year period.
