Question 1064643: Hi, folks!
Good afternoon!
It's my first question here. I've been searchin for a solution to the present mathematical problem, but I haven't still achieved it on my own. My field of studies is in law, not in maths, but I need to solve this problem...
Eternally grateful already.
My problem is that I don't know how to identify the math field, first, and the right math enunciation to find the right solution of the math problem. Can you help me please, giving me some advice or even a solution?
So, what's my math problem?
I have a portfolio with 2133 as TOTAL NUMBER of ISSUED RIGHTS; the price of rights is permanently changing in market, just like in stock market; each right allows you to buy 15 new shares, paying 0.094 for one of those 15 shares, thus the cost to underwrite one right is 15*0.094.
I want to sell the minimum rights possible in order to obtain the precise liquidity to pay the cost of the possible maximum number of rights. It's like an optimization value I look for... The minimum in sell to pay entirely the cost of remaining rights not sold.
Can you help me?
Eternally grateful already.
My best regards.
I've tried this formula...
xy=(2133y-xy)*(0.094*15)
But i feel it's missing something...
