Michele invests some of her money in a mutual fund that quickly goes sour, losing 50% of its value each day for a week. Which of the following COULD NOT be the value of Michele’s investment at the close-of-business any day that week?

$0.00

$133.00

$250.05

$1575.00

$10000.00

Suppose she invests n$ in the starting then in the subesequent days the money left after the day will be

n/2, n/4, n/8, n/16, n/32

Since the amont is a multiple of n so the amount can never be 0 , as in this case the initial investment itself will be zero.

So, answer will be A

Hope it helps!
