Answer:

  C.  x ≈ 0.28

Step-by-step explanation:

A graphing calculator solution is attached. It shows ...

  x ≈ 0.28

__

You can divide both sides of the given equation by 5, then take natural logs and divide by 5 again.

  5e^(5x) = 20 . . . . . . given

  e^(5x) = 4 . . . . . . . . divide by 5

  5x = ln(4) . . . . . . . . take natural logs

  x = ln(4)/5 . . . . . . . divide by 5

  x ≈ 0.277259 ≈ 0.28
