Karen invested $2,000 in a special savings account.

Answer:

D. $512,000

Step-by-step explanation:

Well if the balance doubles every 5 years, then dividing 40 by 5 gives us the number of times the money will double, which is 8. We can then turn this into the equation $2000(2^{8})$ . $2^8$ can be simplified to 256. Multiply that by 2000 and we get our answer, 512000. Hope this helps!
