For continuously compounded interest, you need a formula that involves the constant e.
Do you know the formula?

Yes I do, A=Pe^rt

The thing that's confusing me is the 3.25 on problem #50. Do I write it as .325?

Answer 10

Is 51 B?

Answer 11

Yes. ^^

Answer 12

What does the n stand for in 53?

Answer 13

@AkashdeepDeb

Answer 14

n is how many compoundings happen per year.
t is the number of years.

Answer 15

r is interest rate written as a decimal, so 3% means r = 0.03

Answer 16

so n is going to be 4 right?

Answer 17

@Yothatboy
Were you able to answer 52 and 53?

Answer 18

Oh wait, 52 is C. Right?

Sorry.
n = 4 for problem 52 only.
For problem 53, use the continuous compounding formula.

53 D, correct
