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

### Instruction:
Milly's babysitter charges $16/hour. Milly is considering switching to a new babysitter who charges $12/hour, but also charges an extra $3 for each time the kids scream at her. If Milly usually hires the babysitter for 6 hours, and her kids usually scream twice per babysitting gig, how much less will the new babysitter cost?

### Response:
 Kwanza, tunahitaji kujua kiasi cha jumla ambacho mlinzi wa kwanza anatoza. Tunafanya hivyo kwa kuzidisha kiwango chake cha kila saa na idadi ya masaa anayofanya kazi: 16 * 6 = <<16*6=96>>96 dola.
Kisha, tunapata kiasi cha msingi ambacho mlinzi wa pili anatoza kwa kuzidisha kiwango chake cha kila saa na idadi ya masaa anayofanya kazi: 12 * 6 = <<12*6=72>>72 dola.
Kwa kuwa mlinzi anatoza kwa ajili ya kelele mbili, tunazidisha 2 na 3 dola kwa kila kelele: 2 * 3 = <<2*3=6>>6 dola.
Tunahesabu kiasi cha jumla ambacho mlinzi wa pili anatoza kwa kuzidisha kiasi cha msingi na malipo ya ziada: 72 + 6 = <<72+6=78>>78 dola.
Kisha tunatoa kiasi cha jumla cha mlinzi wa pili kutoka kwenye kiasi cha jumla cha mlinzi wa kwanza ili kupata tofauti: 96 - 78 = <<96-78=18>>18 dola.
