B. $513,361

E. $1,750,000

this is what I did but I'm not gettinthe rigth answer how I came up with the $28 was by 1,820,000/65,000=28
1/(n+1)
1/(3+1)=1/4=25 or 25%
25% of 250,000 shares =10,000+1 0r10,001
=10,001*28
$280,028 this is not a choice

How many shares will he need? Choice (B), for example, will give him exactly one share more than 1/3 of the outstanding shares. Choice (D), on the other hand, leaves him holding 125,001 shares--exactly one share more than half of the outstanding shares.
