### Instruction:
 John alipata $18 Jumamosi lakini alifanikiwa kupata nusu ya kiasi hicho Jumapili. Alipata $20 mwishoni mwa wiki iliyopita. Anahitaji kiasi gani cha pesa zaidi ili aweze kupata $60 anazohitaji kununua kifaa cha kuchezea pogo kipya?


### Response:
 Mwishoni mwa wiki iliyopita, John alipata $18 Jumamosi + $20 Jumapili = $<<18+20=38>>38
Mwishoni mwa wiki hii, John alipata $18 Jumamosi / 2 = $<<18/2=9>>9 Jumapili
Hii inamaanisha kuwa katika wiki mbili, John amepata $38 + $9 = $<<38+9=47>>47
Hivyo, bado anahitaji $60 - $47 = $<<60-47=13>>13 zaidi kununua kifaa cha kuchezea pogo.
