During a period of 6 months, megacorp had monthly profits of $3.2 million, $1.8 million, and $6.4 million. two months had losses of $4.5 million and $2.7 million. the net profit was $7.5 million. what happened in the month that is not included in the problem data?

1. Add up all the profits:
3.2 + 1.8 + 6.4 = $11.4 million
2. Add up all the losses:
4.5 + 2.7 = $7.2 million
3. Profits - Losses = Total Profit so far
$11.4 million - $7.2 million = $4.2 million 
4. What happened in the last month?
The net profit is $7.5 million. This means the last month must have had a profitable month to equal $7.5 million. 
7.5 - 4.2 = $3.3 million profit in the last month
