X=number of 3 wheel scooters
Y=number of 4 wheel scooters
X+Y=50 : X=50-Y
3X+4Y=160 number of wheels
3(50-Y)+4Y=160 then: Y=160-150=10
X=50-Y=50-10=40
Then:
40 x 3 wheel scooters and 10 x 4 wheel scooters

To use all 50 bodies, you have to make 50 scooters. The wheels work out to 40 with 3 wheels (120) and 10 with for wheels (40) for the total 160 wheels.
