Stem and Leaf Plots

City A and City B each took a survey of 30 households to see how much people spent on groceries each week. The results are presented above in the dual stem and leaf plot. If we assume that only families will spend more than 65 dollars per week, and if you spend 65 dollars or less you are living with at most one other person, how many families took the survey in City A? City B? Which city surveyed more families?
