Answer:
The answer is: The original group of lottery winners was made up of 5 people.
Explanation:
The total prize amount was $35,000,000 with each original winning ticket holder earning $7,000,000.
$35,000,000 / 5 = $7,000,000 for each winner
When 2 more winning ticket holders show up, the total prize has to be redivided to include them.
$35,000,000 / 7 = $5,000,000 for each winner
