Interest=Principal*Rate*Time \\ 450=2000*0.05*Time \\ 450=100*Time \\   \frac{450}{100} =Time \\ 4.5=Time

Therefore the time needed is 4 and a half years.

Solution :

principal = P 2 000
rate = 5%
interest = P 450

to solve for the time use this formula :

time =  \frac{interest}{(principal)(rate)}

time = \frac{P 450}{(P 2 000)(0.05)}

time = \frac{P 450}{(100)}

time = 4.5 or  4  \frac{1}{2}
