The ratio of empty to full parking spaces is 3 to 5.
In other words: # of empty spaces/# of full spaces = 3/5
If there are 940 full parking spaces in the lot, how many spaces are empty?
Let x = the number of empty spaces
Since the ratio must hold we can write: x/940 = 3/5
Cross multiply to get: 5x = (3)(940)
Solve: x = 564
Answer: D

Full Parking space \(= 940\)
\(5x = 940\)
\(x = 188\)
Empty spaces \(= 3x = 3*188 = 564\)
