Jane counts two zebras with 17 stripes each, a zebra with 36 stripes, and another zebra with half that many stripes. How many stripes do the zebras have on average?
First find the number of stripes the last zebra has: 36 stripes / 2 = <<36/2=18>>18 stripes
Then find the total number of stripes the first two zebras have: 2 zebras * 17 stripes/zebra = <<2*17=34>>34 stripes
Then add the number of stripes the last two zebras have: 18 stripes + 34 stripes + 36 stripes = <<18+34+36=88>>88 stripes
Then divide the number of stripes by the number of zebras to find the average number of stripes per zebra: 88 stripes / 4 zebras = <<88/4=22>>22 stripes/zebra
