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

### Instruction:
 Mkulima anapanda mahindi. Kwa kila mbegu 4 anazopanda, anapata sikio moja la mahindi, ambalo anaweza kuuza kwa $.1. Inagharimu $.5 kununua mfuko wenye mbegu 100. Ikiwa anapata faida ya $40, aliuza masikio mangapi?


### Response:
 Inagharimu $.005 kwa kila mbegu, kwa sababu .5 / 100 = <<.5/100=.005>>.005
Inagharimu $.02 kukuza sikio moja la mahindi, kwa sababu .005 x 4 = <<.005*4=.02>>.02
Kwa kila sikio la mahindi anapata faida ya $.098 kwa sababu .1 - .02 = .08
Ameuza masikio 500 kwa sababu 40 / .08 = <<40/.08=500>>500
