The U. S. federal debt as a fraction of GDP in year 2050 will be 77%

Explanation:

According to the given data we have the following:

Debt in the end of 2018 = 104% of GDP

Nominal GDP growth = 3%

Interest on debt = 2%

In order to calculate What will be the U. S. federal debt as a fraction of GDP in year 2050 first we have to calculate the debt in 2050 using the following formula:

Debt in 2050 = Current Debt * (1+r%) n

Debt in 2050 = 104*1.0232 = 196

Next, we would have to calculate the GDP in 2050 using the following formula:

GDP in 2050 = Current GDP * (1+r%) n

GDP in 2050 = 100*1.0332 = 257.5

Therefore, Debt as percentage of GDP in 2050 = 196 / 257 = 77%
