Answer:

C. $5,069.96

Step-by-step explanation:

You are given ...

  • P = 3700
  • r = 0.045
  • t = 7

Put these values in the formula where the corresponding variable is, then do the arithmetic.

... A = 3700·e^(0.045·7)

... = 3700·e^0.315

... ≈ 3700·1.3702593

... ≈ 5069.9594...

The balance will be $5069.96.
