Answer:

We need to put $801.88 amount in the bank.

Explanation:

given that

t=3 yr

Need amount $850 after 3 yr so P= $850

Interest rate=2%

We know that for simple interest


P=A\left(1+(rt)/(100)\right)

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


850=A\left(1+(2* 3)/(100)\right)

So A=$801.88

We need to put $801.88 amount in the bank.
