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

### Instruction:
Krystian works in the library. He borrows an average of 40 books every day. Every Friday, his number of borrowed books is about 40% higher than the daily average. How many books does he borrow in a week if the library is open from Monday to Friday?

### Response:
 Ijumaa, anakopa vitabu 40% zaidi ya siku nyingine. 40% ya 40 ni 40/100*40 = <<40/100*40=16>>16, hivyo anakopa vitabu 40+16 = <<40+16=56>>56 Ijumaa.
Anakopa vitabu 40 siku nyingine za wiki, hivyo anakopa vitabu 40*4 = <<40*4=160>>160 siku nyingine za wiki.
Anakopa 160 + 56 = <<160+56=216>>216 vitabu jumla katika wiki moja.
