The new parking lot has spaces for 450 cars. The ratio of spaces for full-sized cars to compact cars is 11 to 4. How many spaces are for full-sized cars? How many spaces are for compact cars?
---------------------
11 to 4 is the same as 11x to 4x where 4x is the number of compact cars.
----
Equation:
11x + 4x = 450
15x = 450
x = 30
----
# of compact cars = 4x = 4*30 = 120
# of full-sized cars = 11x = 11*30 = 330
