B

96 trucks and 110 cars

A

Step-by-step explanation:

There are two ways to do this, fast and slow

Fast: Division

divide 80 by five and you get 16, since there are 4 for every 5 cars multiply 16 by 4 and you get 64 proving A correct

Slow: Addition

5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5=80

4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4=64
