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

### Instruction:
The number of Christmas presents David found was twice as many as the number of birthday presents. If David found a total of 60 Christmas presents, how many presents did he get all together?

### Response:
 Zawadi za Krismasi ambazo David alipata ni mara mbili ya idadi ya zawadi za siku ya kuzaliwa, maana yake kuna zawadi 60/2 = 30 za siku ya kuzaliwa.
David alipata jumla ya zawadi 60+30 = <<60+30=90>>90 kwa jumla.
