Problema Solution
Bill has 5 times as many baseball cards as Fred. Tim has 3 fewer than 4 times as many baseball cards as Fred. In all they have 167 baseball cards. How many does each have?
Answer provided by our tutors
let 'x' represent the number of cards Fred has, then '5x' represents the number Bill has and '4x-3' represents the number Tim has:
167 = x + 5x + 4x-3
solving for 'x' we have x=17
5*17 = 85
4*17 - 3 = 65
Fred has 17 cards, Tim has 67 cards and Bill has 85 cards
