PLEASE I NEED AN ANSWER NOW
You invest $200 when you turn 18 years old. You are told
your money will double every 4 years. How much money
will you have when you are 42 years old?

(and maybe if you can answer this part, thank you)
If it doubles every 6 years instead of every 4, how would your
investment worth change?
(again, this part is optional)

$12,800

Step-by-step explanation:

42-18= 24

24 is the years the money is growing.

24/4=6

200x2x2x2x2x2x2=12,800

if it doubles every six years it would be 200x2x2x2x2=3,200

the difference is 9,600

At 42 years old you would have $2278.13.

If it doubles every six years,  then you would have $1012.50.

Step-by-step explanation:

the answer is (-4,-4)
