To find the increase in the debt over the 50-year period, we can subtract the debt in 1971 from the debt in 2021.
2021 debt - 1971 debt = (2.9617 x 10^13) - (3.98 x 10^11)
= 2.9617 x 10^13 - 3.98 x 10^11
= 2.9617 x 10^13 - 2.9617 x 10^12 (subtracting in scientific notation)
Now we can combine the terms with the same power of 10:
2.9617 x 10^13 - 2.9617 x 10^12 = (2.9617 - 0.29617) x 10^13
= 2.66553 x 10^13
So, the debt increased by $2.66553 x 10^13 or in standard notation, $26,655,300,000,000.
Therefore, the answer is not listed among the options provided.
