He has half as many out of school friends as classmates on his contact list. He also has his two parents and his sister on his contact list. How many people are on Jerome's contact list?
Step-by-step reasoning process: Jerome has 20 classmates on the list, and has half as many out of school friends on there so he has 20 / 2 = 10 out of school friends on the contact list. He has 2 parents and 1 sister on the contact list, for 2 + 1 = 3 family members on the contact list. Adding the classmates, out of school friends and family members together we get 20 + 10 + 3 = 33 people on his contact list.
