Three people are on an elevator.The woman weighs three times as much as the child.The man weighs 7 pounds more than 5 times as much as the child. If the child weighs p pounds, represent in terms of p, the combined weight of the child, the woman, and the man.
child = p
woman = 3 p
man = 5 p +7 (pretty fat)
sum= p + 3 p + 5 p + 7 = 9 p + 7
