Answer:
7 years
Step-by-step explanation:
Simple interest is given by
I = PRT where I is the interest, P is the principle r is the rate and t is time
If we have 249 in the account and started with 200,
the interest is 249-200 = 49
The principle is 200 and the rate is 3.5% or in decimal form .035
Putting into the equation
49 = 200 (.035) t
49 =7t
Divide each side by 7
49/7 = 7t/7
7 =t
It will take 7 years
