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

### Instruction:
 Nadia alitumwa dukani kununua maua 20 ya waridi na 3/4 ya maua hayo ya lily. Ikiwa waridi hugharimu $5 kila moja na lily hugharimu mara mbili zaidi, hesabu jumla ya pesa ambazo Nadia alitumia kununua maua.


### Response:
 Gharama jumla ya waridi ni 20*5 = $<<20*5=100>>100
Nadia alinunua 3/4*20 = <<3/4*20=15>>15 lily.
Kila lily inagharimu 5*2 = $<<5*2=10>>10
Alitumia $10*15 = $<<10*15=150>>150 kwa lily.
Jumla ya pesa ambazo Nadia alitumia kununua maua ni $100+$150 = $<<100+150=250>>250
