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

### Instruction:
Martha receives a daily allowance of $12. She decides to save half of this amount every day. In the first week she kept her commitment with the exception of one day when she saved only a quarter of this amount. How much has she saved at the end of this week?

### Response:
 Nusu ya $12 ni (1/2)*$12 = $6
Kuna siku 7 katika wiki hivyo ikiwa aliokoa nusu kila siku isipokuwa moja basi aliokoa nusu kwa siku 7-1 = <<7-1=6>>6
Ikiwa aliokoa $6 kwa siku 6 basi aliokoa $6*6 = $<<6*6=36>>36
Robo ya $12 ni (1/4)*$12 = $<<12*1/4=3>>3
Ikiwa aliokoa robo mara moja basi aliokoa $3+$36 = $<<3+36=39>>39
