### Instruction:
James earns $20 an hour while working at his main job.  He earns 20% less while working his second job.  He works 30 hours at his main job and half that much at his second job.  How much does he earn per week?

### Response:
 Kazi yake ya pili inamlipa $20*0.8 = <<20*0.8=16>>16 dola kwa saa.
James anafanya kazi masaa 30 kazi yake kuu na 15 masaa kazi yake ya pili.
Jumla ya masaa anayofanya kazi ni 30 + 15 = <<30+15=45>>45 masaa.
Jumla anayopata ni 30*20 + 15*16 = <<30*20+15*16=600+240=840>>840 dola kwa wiki.
