### Instruction:
Chelsea made 4 batches of cupcakes for the bake sale. The cupcakes took 20 minutes to bake and 30 minutes to ice per batch. How long did it take Chelsea to make the cupcakes?

### Response:
 Chelsea alipika vikundi 4 x dakika 20 = <<4*20=80>>80 dakika za keki.
Chelsea alipaka glasi vikundi 4 x dakika 30 = <<4*30=120>>120 dakika za keki.
Jumla ya dakika alizotumia Chelsea kufanya keki hizo kwa ajili ya mauzo ni 80 + 120 dakika = <<80+120=200>>200 dakika.
