Olga has three stripes on the side of each of her tennis shoes.  Rick has one less stripe per shoe than does Olga.  But Hortense has double the number of stripes on her tennis shoes as does Olga.  In total, what is the combined number of stripes on all of their pairs of tennis shoes?
Rick has one less than three stripes, or 3-1=2 stripes on each tennis shoe.
Hortense has double the 3 stripes that Olga has, or a total of 3*2=<<3*2=6>>6 stripes per shoe.
Since each of them has two tennis shoes per pair, then the total number of stripes on all of their shoes is 2*(3+2+6)=<<2*(3+2+6)=22>>22 stripes
