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

### Instruction:
 Kwenye duka fulani la magari, 15% ya magari yanagharimu chini ya $15000 na 40% ya magari yanagharimu zaidi ya $20000. Ikiwa kuna magari 3000 kwenye duka hilo, magari mangapi yanagharimu kati ya $15000 na $20000?


### Response:
 15% ya magari 3000 ni (15/100)*3000 = <<(15/100)*3000=450>>450 magari.
40% ya magari 3000 ni (40/100)*3000 = <<(40/100)*3000=1200>>1200 magari.
Jumla ya magari yanayogharimu chini ya $15000 au zaidi ya $20000 ni 450+1200 =<<450+1200=1650>>1650 magari.
Ikiwa kuna magari 3000 kwenye duka, idadi ya magari yanayogharimu kati ya $15000 na $20000 ni 3000-1650 = <<3000-1650=1350>>1350.
