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

### Instruction:
 Madeline spends 18 hours a week in class. She spends 4 hours per day working on homework. She spends 8 hours per day sleeping. She works part-time 20 hours per week. How many hours left over does Madeline have?


### Response:
 Madeline spends 4*7=<<4*7=28>>28 hours on homework.
She spends 8*7=56 hours sleeping.
She works 20*1=<<20*1=20>>20 hours at her part-time job.
Thus, she is busy 18+28+56+20=<<18+28+56+20=122>>122 hours per week.
There are 7*24=<<7*24=168>>168 hours per week.
Thus, Madeline has 168-122=<<168-122=46>>46 hours left over.
