A parking garage of a mall is four stories tall. On the first level, there are 90 parking spaces. The second level has 8 more parking spaces than on the first level, and there are 12 more available parking spaces on the third level than on the second level. The fourth level has 9 fewer parking spaces than the third level. If 100 cars are already parked, how many cars can be accommodated by the parking garage?

How many parking spaces are on the second level? ** The second level has 90 + 8 = <<90+8=98>>98 parking spaces.
How many parking spaces are on the third level? ** The third level has 98 + 12 = <<98+12=110>>110 parking spaces.
How many parking spaces are on the fourth level? ** The fourth level has 110 - 9 = <<110-9=101>>101 parking spaces.
How many cars can be accommodated by the parking garage? ** So the parking garage can accommodate 90 + 98 + 110 + 101 = <<90+98+110+101=399>>399 cars.
How many cars can be accommodated by the parking garage? ** Thus, the parking garage can still accommodate 399 - 100 = <<399-100=299>>299 cars.
