Given the statement:

$100 dollars is deposited into an account and the account doubles every 8 years.

Determine how much will be in the account after 40 years.

Solution:

Divide 40 by 8 then we double the amount that times.

= 40/8

= 5

8th year= 100(2)

8th year =200

16th year = 200(2)

16th year = 400

24th year = 400(2)

24th year = 800

32nd year = 800(2)

32nd year = 1600

40th year = 1600 (2)

40th year = $3200

Final answer:
The amount after 40 years is $3200
