Thanks Guys!
We can plug in the answer choices, which represent the number who own both types of cars.
Answer choice C: 7 own both types of cars.
Since total Fords = 16, 16-7 = 9 own only Fords.
Since total Toyotas = 11, 11-7 = 4 own only Toyotas.
Total who own only 1 type of car = 9+4 = 13.
Doesn't work. Eliminate C.
Since just a few more must own only 1 type of car, slightly fewer must own both.
The correct answer is
B.
Answer choice B: 6 own both types of cars.
Since total Fords = 16, 16-6 = 10 own only Fords.
Since total Toyotas = 11, 11-6 = 5 own only Toyotas.
Total who own only 1 type of car = 10+5 = 15. Success!
