Question

A restaurant offers a buffet dinner at group prices. The buffet costs the restaurant $6 per person. How large a group can the restaurant serve without losing money?


P. S. I came up with a group of ten person that they could serve. Please let me know if this is wrong.

Thank-you!


That's what I also found using the expression I gave in a previous post. I hope you verified that expression for the first 5 terms as well.


y=3(x+5)(x-2)
