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

### Instruction:
Katie has 13 pink marbles. She has 9 fewer orange marbles than pink marbles. She has 4 times as many purple marbles as orange marbles. How many marbles does Katie have in all?

### Response:
 Pata idadi ya mabulinge ya machungwa. Mabulinge 13 - mabulinge 9 = <<13-9=4>>4 mabulinge
Pata idadi ya mabulinge ya zambarau. Mabulinge 4 x 4 = <<4*4=16>>16 mabulinge
Ongeza idadi ya kila rangi ya mabulinge ili kupata idadi jumla ya mabulinge. Mabulinge 4 + mabulinge 13 + mabulinge 16 = <<4+13+16=33>>33 mabulinge
