In a corporation, the shareholders receive 1 vote for each share of stock they hold, which is usually based on the amount of money the invested in the company. Suppose a small corporation has two people who invested $30,000 each, two people who invested $20,000 each, and one person who invested $10,000. If they receive one share of stock for each $1000 invested, and any decisions require a majority vote, set up a weighted voting system to represent this corporation's shareholder votes.

shareholders A and B will each have 30 votes (each invested $30,000)

shareholders C and D will each have 20 votes (each invested $20,000)

shareholder E will have 10 votes (only invested $10,000)

total number of possible votes = (30 x 2) + (20 x 2) + 10 = 110 votes

any decision must be approved by more than 50% of the votes, but since the votes are bundled in tens, 60 votes are needed.
