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

### Instruction:
Erica lives near a lake where most locals sell fish as their main source of income, earning $20 per kg of fish. She goes out fishing today and catches twice as many fish as she caught in total in the past four months. If Erica trawled 80 kg of fish in the past four months, not including today, how much money will she have earned in the past four months including today (assuming she sells all her fish)?

### Response:
 Ikiwa katika miezi minne iliyopita Erica alivua kg 80 ya samaki, bila kuhesabu leo, basi leo amevua kg 80 * 2 = <<80*2=160>>160 ya samaki.
Kipato cha leo ni kg 160 * $20/kg = $<<160*20=3200>>3200.
Katika miezi minne iliyopita, Erica amepata $80 kg * $20/kg = $<<80*20=1600>>1600.
Kwa kuhesabu kipato cha leo, Erica amepata jumla ya $3200 + $1600 = $<<3200+1600=4800>>4800.
