The interest formula is :


I=P* r* t

where I is the interest

P is the Initial amount

r is the rate of interest

and t is the time in years

From the problem,

P = 1000

I = 100

r = 7% or 0.07

Using the formula above, the time in years will be :


\begin{gathered} 100=1000(0.07)t \\ t=(100)/(1000(0.07))=1.43 \end{gathered}

1.43 years
