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

### Instruction:
Calvin and Phoebe each have 8 more pastries than Frank but only five less than Grace. If Grace has 30 pastries, calculate the total number of pastries that the four have?

### Response:
 Frank ana mikate 8 + 5 = <<8+5=13>>13.
Calvin na Phoebe kila mmoja ana mikate 8 zaidi ya Frank, hivyo wana mikate 21.
Grace ana mikate 30.
Jumla ya mikate ni 13 + 21 + 30 = <<13+21+30=64>>64.
