Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
John decides to take up illustration.  He draws and colors 10 pictures.  It takes him 2 hours to draw each picture and 30% less time to color each picture.  How long does he spend on all the pictures?

### Response:
 Kuchora kunachukua masaa 2*10=<<2*10=20>>20
Anachorea kila picha .3*2=<<.3*2=0.6>>0.6 masaa chini ya muda wa kuchora
Hivyo inachukua 2-.6=<<2-.6=1.4>>1.4 masaa kuchorea kila picha
Hivyo inachukua 1.4*10=<<1.4*10=14>>14 masaa kuchorea picha zote
Hivyo jumla inachukua 14+20=<<14+20=34>>34 masaa
