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.

**helper**, Thursday, January 13, 2011 at 10:50pmx = number of cars

y = number of motorcycles

4x = number of tires for cars

2y = number of tires for motorcycles

x + y = 500

4x + 2y = 1650

solve together

you should get

325 cars

175 motorcycles
