To find the increase in the national debt over the 50-year period, we need to subtract the debt in 1971 from the debt in 2021.
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = 2.9617×10^13 - 3.98×10^11
To subtract these numbers, we need to make sure they are written in scientific notation with the same exponent.
2.9617×10^13 = 29.617×10^12
3.98×10^11 = 0.398×10^12
Debt increase = (29.617×10^12) - (0.398×10^12)
Debt increase = 29.219×10^12
Therefore, the increase in the national debt over the 50-year period is $2.9219×10^13.
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. (1 point)
