Example: The kid wants a birthday party at Chucky Cheese. I(company) have 100 bucks set aside to spend on it and no more. Chucky charges 5 bucks per kid (divi), so my kid can only invite 20 kids (float), but a rumor went around his class about the party and 60 kids showed up. So now how am I going to pay for those extra kids and still stay within my budget for the party?
