Question

A 500 space parking lot is packed with motorcycles and passenger cars, with only one vehicle in each space. How many motorcycles & cars r there if the total number of tires on the parked vehicles is 1650?

I think I have to do this in some kind of equation format, I am so confused.

Answer 1

175 motorcycles, 325 cars
motorcycles represented as x and cars, y

2x+4y=1650
2(500-y)+4y=1650
1000-2y+4y=1650
2y=650
y=325

2x+1300=1650
2x=350
x=175
