### Instruction:
 Mary anapata $20 kwa kufua magari na $40 kwa kutembeza mbwa kila mwezi. Ikiwa anaweka nusu ya pesa hizo kila mwezi, itamchukua muda gani kuokoa $150?


### Response:
 Kila mwezi anapata 20+40=$<<20+40=60>>60
Anahifadhi 60/2=$<<60/2=30>>30 kila mwezi
Kuokoa $150 itamchukua 150/30=<<150/30=5>>5 miezi
