A charity is considering the possibility of having a benefit night at two different restaurants. The owner of the local Italian restaurant has offered to make a donation of $20 and $6 per
diner that night. On the other hand, the owner of the Mexican restaurant has said he could
contribute $45 plus $1 per diner. Based on the number of diners who have promised to
participate in the event, it appears that each restaurant would donate the same total amount.
