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

### Instruction:
Mark has kangaroos and goats.  Kangaroos have two legs and goats have four legs.  If he has 23 kangaroos and three times as many goats as kangaroos what is the total number of legs of all his animals?

### Response:
His kangaroos have a total of 23*2=<<23*2=46>>46 legs
He has three times as many goats as kangaroos so he has 3*23=<<3*23=69>>69 goats
The goats have 69*4=<<69*4=276>>276 legs
So in total his animals have 276+46=<<276+46=322>>322 legs
