Answer

Explanation:

Step1: Calculate total number of families

The total number of families surveyed is 300.

Step2: Calculate number of families with two or more cars

The number of families with two or more cars is (132 + 93=225).

Step3: Calculate percentage of families with two or more cars

The percentage is (\frac{225}{300}\times100% = 75%).

Step4: Calculate number of non - homeowner families

The number of non - homeowner families is (93+54 = 147).

Step5: Calculate percentage of non - homeowner families

The percentage is (\frac{147}{300}\times100%=49%)

Answer:

(a) 75% (b) 49%
