### Response:
 Anahitaji kuweka mafuta ya jua kila baada ya masaa 2 kwa masaa 16 hivyo anahitaji kuweka mara 16 / 2 = <<16/2=8>>8
Anahitaji unga wa 3 kwa kila matumizi na atatumia mara 8 hivyo anahitaji 3*8 = <<3*8=24>>24 unga
1 chupa ina unga wa 12 na anahitaji unga wa 24 hivyo ni 24 / 12 = <<24/12=2>>2 chupa
Kila chupa inagharimu $3.5 na anahitaji chupa 2 hivyo ni 3.5 * 2 = $<<3.5*2=7>>7
