### Instruction:
 Kipande kimoja cha nyama ya ng'ombe kina kubu 4. Kipande kimoja cha nyama ya ng'ombe ambacho kina gharama ya $25 kinaweza kukatwa katika kubu 80. Simon anapaswa kutumia kiasi gani ili kutengeneza kipande cha nyama cha kubu 40?


### Response:
 Kipande kimoja cha nyama ya ng'ombe kinaweza kutengeneza kubu 80/4 = <<80/4=20>>20.
Ili kutengeneza kubu 40, Simon anahitaji kipande cha nyama cha 40/20 = <<40/20=2>>2.
Simon anapaswa kutumia $25 x 2 = $<<25*2=50>>50.
