Answer:
We need to put $801.88 amount in the bank.
Step-by-step explanation:
given that
t=3 yr
Need amount $850 after 3 yr so P= $850
Interest rate=2%
We know that for simple interest

Where r is the Interest rate,t is the time,A is the present amount and P is principle amount after t time.
Here given that P= $850
So now putting the values

So A=$801.88
We need to put $801.88 amount in the bank.
