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

### Instruction:
 Maria anakusanya stempu na anataka kuongeza ukusanyaji wake. Amekusanya stempu 40 hadi sasa na anapanga kuwa na 20% zaidi. Maria anataka kukusanya stempu ngapi jumla?


### Response:
 Maria anapanga kuwa na stempu 20/100 * 40 = <<20/100*40=8>>8 zaidi katika ukusanyaji wake.
Hii inamaanisha anataka kuwa na stempu 40 + 8 = <<40+8=48>>48.
