### Instruction:
 Mark hufanya kazi kila siku nyingine kwa wiki 2. Kwa kila kazi, yeye hucheza nyimbo 3. Nyimbo 2 ni za dakika 5 na nyimbo ya mwisho ni mara mbili ya hiyo. Alipiga kwa dakika ngapi?


### Response:
 Alicheza kazi 7*2 = <<7*2=14>>14
Nyimbo ndefu ilikuwa dakika 5*2=<<5*2=10>>10
Hivyo kila kazi ilikuwa dakika 5+5+10=<<5+5+10=20>>20
Hivyo alipiga dakika 14*20=<<14*20=280>>280
