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

### Instruction:
Shane wants to take as many photos as possible this year. He takes 146 photos in the first 2 months of the year. In January, he takes 2 photos every day. The rest of the photos were taken in February. If in February he took an equal number of photos each week, how many photos did Shane take each week in February?

### Response:
 Mwezi Januari, Shane anachukua picha 2 kila siku, ambayo inamaanisha anachukua picha 2 * 31 = <<2*31=62>>62 picha.
Hivyo lazima awe amechukua picha 146 jumla ya picha katika miezi 2 ya kwanza ya mwaka - 62 picha za Januari = 146 - 62 = 84 picha mwezi Februari.
Kwa kuwa anachukua idadi sawa kila wiki, lazima achukue 84 picha / 4 wiki = <<84/4=21>>21 picha kila wiki.
