The number in question is 7.5
Step-by-step explanation:
15 ÷ 2 = 7.5
Why divide by 2? Because dividing by 2 is the <u>inverse</u> of multiplying by 2. To double-check our solution, just multiply 7.5 by 2... and 15!!
N = N₀* 
where N is how much you currently have
N₀ is the starting amount
t is the time
and h is the half life of the substance.
If you would like to know how much is the stock worth now, you can calculate this using the following steps:
1 year: 6 1/2 % of $875 = 6.5% * $875 = 6.5/100 * 875 = $56.875
$875 + $56.875 = $931.875
2 year: 6 1/2 % of $931.875 = 6.5% * $931.875 = 6.5/100 * 931.875 = $60.572
$931.875 + $60.572 = $992.447
3 year: 6 1/2 % of $992.447 = 6.5% * $992.447 = 6.5/100 * 992.447 = $64.509
$992.447 + $64.509 = $1056.956 = $1056.96 = $1057
The correct result would be: The stock is worth $1057 now.
