Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Sakafu ya pili ina nafasi za kuegesha magari 90 + 8 = <<90+8=98>>98.
Sakafu ya tatu ina nafasi za kuegesha magari 98 + 12 = <<98+12=110>>110.
Sakafu ya nne ina nafasi za kuegesha magari 110 - 9 = <<110-9=101>>101.
Hivyo, ghorofa ya kuegesha inaweza kuegesha magari 90 + 98 + 110 + 101 = <<90+98+110+101=399>>399.
Hivyo, ghorofa ya kuegesha bado inaweza kuegesha magari 399 - 100 = <<399-100=299>>299.
