Ted the T-Rex was planning to bring potato salad to the dinosaur picnic.  He knows that an adult dinosaur will eat 10 lbs of potato salad, and a child will eat half as much as an adult.  If there will be 20 adults and 5 children at the picnic, how many pounds of potato salad does Ted need to bring to the picnic if he hopes to have enough to feed everyone?
