If a country's debt-to-gdp ratio is currently 15% and its debt is expected to grow from 2 trillion dollars to 3 trillion dollars in the next 5 years what will the country's gdp have to be in five years to maintain the current debt-to-gdp ratio

If the current debt is 2 trillion dollars, then the GDP must be 2/1.15=$1.7391 X 10^12. If the ratio of 15% must be maintained in 5 years time, then the GDP must grow to: 3/2 X 1.7391 X 10^12

=$2.60865 X 10^12. Because: 3 X 10^12/2.60865 X 10^12=1.15=15%

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

correct answer is b. 27/8
