Answer:
9
Step-by-step explanation:
You use the stem as the first number and leaves as second so ppl who live less than 40 miles live one of them lives 21 miles away another lives 22,23,27,28,29,30,31,34 and the others live more than that starting by ppl who live 47 miles away so if you count 21,22,23,27,28,29,30,31,34 you'll come up with 9 of them who live less then 40 miles away from work
hopefully you got it
