To find the increase in the national debt over the 50-year period, subtract the debt in 1971 from the debt in 2021:
$2.9617×10^13 - $3.98×10^11 = $2.9219×10^13
Therefore, the debt increased by $2.9219×10^13. (Answer: $2.9219×10^13)
To find the increase in the U.S. national debt over the 50-year period from 1971 to 2021, subtract the debt in 1971 from the debt in 2021.
$2.9617×10^13 - $3.98×10^11 = $2.9219×10^13
Therefore, the debt increased by $2.9219×10^13. The correct answer is: $2.9219×10^13.
To find the increase in the U.S. national debt over the 50-year period from 1971 to 2021, you need to calculate the difference between the debt in 2021 and the debt in 1971.
Given that the U.S. national debt was $2.9617×10^13 in 2021 and $3.98×10^11 in 1971, you subtract the debt in 1971 from the debt in 2021:
$2.9617×10^13 - $3.98×10^11
To subtract the values, you need to make sure both numbers have the same exponent (power of 10). In this case, you can convert $3.98×10^11 to the same exponent as $2.9617×10^13, which is $3.98×10^13.
Therefore, the calculation becomes:
$2.9617×10^13 - $3.98×10^13
This gives you:
$2.9617×10^13 - $3.98×10^13 = -$1.0183×10^13
The negative sign indicates a decrease instead of an increase. So the correct answer is:
$1.0183×10^13
Therefore, the debt increased by approximately $1.0183×10^13 over the 50-year period.
