I believe it would be B. If I'm correct, whenever it says something like 3t, you have to multiply the 3 by the unknown number (t) once you know what it is. I'm not 100% sure about this so trust someone else before you trust me because i would hate for you to listen to me and get it wrong...

Hope This Helps,

Answer:

B. the number of times (per year) the account compounds interest

Step-by-step explanation:

The given expression has no exponent. We assume you intend ...

balance = 3,545·1.045^(3t)

This expression for the account balance suggests Cressida invested 3,545 into an account paying interest at an annual rate of 13.5%, compounded 3 times per year. The 3 multiplying the number of years is the number of times interest is compounded per year.
