day 5

It is a busy day at Rappo's Batting Cage, where some of the Little League players come to practice their hitting. Craig and Matt, two good friends, run into each other. "How come  I haven't seen you here before?" Craig asks Matt. "well, our coach brings us every 7 days," Matt said. "How about you?" Craig told hime that their coach brings his team every 4 days. How many days will it be until the two friends see each other again at the batting cage?(Use or Make a Table, they will meet at day 28.)
