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

### Instruction:
Andy is checking to see if all the cars in the parking lot paid for their parking. 75% of the cars have valid tickets, and 1/5th that number have permanent parking passes. If there are 300 cars in the parking lot, how many people tried to park in the lot without paying?

### Response:
 Kwanza tafuta idadi ya magari yenye tiketi halali: 75% * 300 magari = <<75*.01*300=225>>225 magari
Kisha multiply idadi hiyo na 1/5 ili kupata idadi ya magari yenye kadi za maegesho: 225 magari * 1/5 = <<225*1/5=45>>45 magari
Kisha toa magari yote yenye fomu halali za maegesho ili kupata idadi ya magari yaliyopakiwa kinyume cha sheria: 300 magari - 225 magari - 45 magari = <<300-225-45=30>>30 magari
