The U.S. national debt was $2.9617×10^13 in 2021 and $3.98×10^11 in 1971. Find how much the debt increased in the 50-year period.
The increase in debt is calculated by subtracting the initial debt from the final debt:
$2.9617×10^13 - $3.98×10^11
= $2.9617×10^13 - $0.398×10^13
= $2.5637×10^13
The debt increased by $2.5637×10^13, or $25.637 trillion.
thats not right
To find the increase in the U.S. national debt between 1971 and 2021, we need to calculate the difference between the two values.
The debt in 2021 was $2.9617×10^13, and the debt in 1971 was $3.98×10^11.
To simplify the calculations, let's convert both numbers to standard notation:
Debt in 2021 = $29,617,000,000,000
Debt in 1971 = $398,000,000,000
Now, to find the increase in debt, we subtract the debt in 1971 from the debt in 2021:
$29,617,000,000,000 - $398,000,000,000 = $29,219,000,000,000
Therefore, the U.S. national debt increased by approximately $29,219,000,000,000 over the 50-year period.
To calculate the increase in the U.S. national debt from 1971 to 2021, you need to subtract the debt in 1971 from the debt in 2021.
Step 1: Convert the given values to their actual numbers.
Debt in 2021: $2.9617 × 10^13
Debt in 1971: $3.98 × 10^11
Step 2: Perform the subtraction.
$2.9617 × 10^13 - $3.98 × 10^11
To subtract these numbers, we need to ensure that the exponents (powers of 10) are the same. To do this, we can rewrite $3.98 × 10^11 as $0.398 × 10^13.
$2.9617 × 10^13 - $0.398 × 10^13 = $2.5637 × 10^13
Therefore, the U.S. national debt increased by approximately $2.5637 × 10^13 (or $25.637 trillion) over the 50-year period from 1971 to 2021.
