To find how much the debt increased in the 50-year period, we subtract the debt in 1971 from the debt in 2021.
2021 debt - 1971 debt = $2.9617×1013 - $3.98×1011
= $2.9617×1013 - $0.398×1013
= $2.5637×1013
Therefore, the debt increased by $2.5637×1013 or $2.9219×1013. So the correct answer is:
$2.9219×1013
To find out how much the U.S. national debt increased in the 50-year period, we need to calculate the difference between the debt in 2021 and the debt in 1971.
The debt in 2021 is given as $2.9617×10^13, and the debt in 1971 is given as $3.98×10^11.
To calculate the increase in debt, subtract the debt in 1971 from the debt in 2021:
$2.9617×10^13 - $3.98×10^11 = $2.9219×10^13.
Therefore, the U.S. national debt increased by $2.9219×10^13 during the 50-year period.
To find how much the U.S. national debt increased in the 50-year period, you need to subtract the debt in 1971 from the debt in 2021.
Debt in 2021: $2.9617×10^13
Debt in 1971: $3.98×10^11
To subtract these numbers, you need to perform a subtraction operation:
$2.9617×10^13 - $3.98×10^11
First, let's subtract the whole numbers:
2.9617 - 3.98 = -1.0183
Next, let's perform the exponent calculation:
10^13 - 10^11 = 10^(13-11) = 10^2 = 100
Finally, let's combine the results:
-1.0183 * 100 = -101.83
The debt increased by $101.83. However, since the question asks for the answer in scientific notation, we need to convert it:
-101.83 = -1.0183 × 10^2
Therefore, the correct answer is $2.9219×10^11.
