19 cars; 20 motorcycles

21 cars; 18 motorcycles

16 cars; 23 motorcycles

Answer 1

Hello!

The answer is: 19 cars; 20 motorcycles.
This is because 4 • 19 + 2 • 20 = 116

The other options are incorrect because:

4 • 16 + 2 • 23 = 110
4 • 21 + 2 • 18 = 120
4 • 23 + 2 • 16 = 124

So, your answer is the second option. ^ I really hope this helped you out! :)
