Quizplus · Accepted Answer

To find out how many own a dehumidifier or a snow blower, we need to add the total number of people who own a dehumidifier and the total number of people who own a snow blower, then subtract the number of people who own both since they were counted twice. 
This can be represented as: (Total dehumidifier owners) + (Total snow blower owners) - (Owners of both)
Plugging in the values given in the problem, we get: 
170 + 130 - 80 = 220. 
Therefore, the correct choice is D. The number of people who own a dehumidifier or a snow blower can be found by adding the number of people who own only a dehumidifier (170 - 80 = 90), the number of people who own only a snow blower (130 - 80 = 50), and the number of people who own both (80). This gives a total of 90 + 50 + 80 = 220. Therefore, option D is the correct answer.
