A table of the business's profits from Jan to April, and the overall profit at the end of each month (assuming we're starting at zero).

Month Profit this month Overall profit
Jan 2 bucks 2 bucks
Feb -50 bucks -48 bucks
Mar -200 bucks -248 bucks
April 1000 bucks hmm...

Hopefully the boss will be slightly less angry about the first three months when he see's how I've professionally used a table for this information!
