Question

researchers asked 300 families whether they were homeowners and how many cars they had. their responses are summarized in the following table.

	two or more cars	no car or one car
not a homeowner	114	48

(a) what percentage of the families are homeowners?
(b) what percentage of the families have no car or one car?

Explanation:

Step1: Calculate total homeowners

Homeowners with no car/one car: 30, with two or more: 108. Total homeowners = 30 + 108 = 138.

Step2: Calculate percentage for (a)

Total families = 300. Percentage = (138 / 300) * 100 = 46%.

Step3: Calculate total no car/one car families

Homeowners: 30, non - homeowners: 48. Total = 30 + 48 = 78.

Step4: Calculate percentage for (b)

Percentage = (78 / 300) * 100 = 26%.

Answer:

(a) 46%
(b) 26%
