A parking lot contains a total of 52 cars and motorcycles. There are a total of 186 tires (not counting spare tires) in the lot. Assuming each car has 4 tires and each motorcycle has 2 tires, determine how many cars and how many motorcycles are in the parking lot.

  • Math -

    cars ---- x
    bikes ----y

    x+y = 52

    4x + 2y = 186 or
    2x + y = 93

    subract:
    x = 41
    then 41 + y = 52 ---> y = 11

    There are 41 cars and 11 bikes.
