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

### Instruction:
Caleb is baking a birthday cake for his grandfather. His grandfather is turning 79 years old. Caleb puts three colors of candles on the cake. He puts one candle for each year for his grandfather. He puts 27 yellow candles, 14 red candles and the rest are blue candles. How many blue candles did he use?

### Response:
 Caleb ameweka mishumaa 27 + 14 = <<27+14=41>>41 kwa miaka 79 ya kwanza ya maisha ya babu yake.
Hivyo, alitumia mishumaa 79 - 41 = <<79-41=38>>38 za bluu kwa miaka iliyobaki.
