Mrs. O’Leary received a bracelet many years ago when her first son was born. At that time, she was given a shamrock charm. She was then given one at the births of her 3 other children. Now she adds one for each of her grandchildren. Her older son has 2 children and her younger son half as many. Her one daughter had a set of triplets and a set of twins. Her other daughter has as many as the two sons together. How many shamrock charms are on the bracelet? What percent of the charms are for her son’s children? What percent of the charms are for her daughter’s children?
