Graduation is 3 years away and you want to have $850 available for a trip. if your bank is offering a 3-year cd (certificate of deposit) paying 2% simple interest, how much do you need to put in this cd to have the money for your trip?

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.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
