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

### Instruction:
 Krystian anafanya kazi katika maktaba. Anakopa wastani wa vitabu 40 kila siku. Kila Ijumaa, idadi ya vitabu anavyokopa ni takriban 40% zaidi ya wastani wa kila siku. Anakopa vitabu vingapi katika wiki ikiwa maktaba inafunguliwa kutoka Jumatatu hadi Ijumaa?


### 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.
