Elaine has invested $575 in a stock that is expected to double every 8 years. what will be the value of the stock in 16 years? a.) $4,600.00 b.) $37,683,200.00 c.) $147,200.00 d.) $2,300.00

The correct option is D.
The initial value of the stock is $575 and it doubles every 8 years, this means that, in the next eight year the value of the stock will be 2 * 575 = $1150.
This amount too will double in the next eight year and the value will become 2* 1150 = $2,300.
Therefore, in 16 years time the share will be worth $2,300.00.
