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

### Instruction:
Aubrie has four cards with the labels W, X, Y, Z printed on them. W is tagged with the number 200, X is tagged with half the number W is tagged with, Y is tagged with the total of X and W's tags and Z is tagged with the number 400. Calculate the total of all the tagged numbers.

### Response:
 Ikiwa kadi yenye herufi X ina nusu ya nambari ambayo kadi yenye herufi W ina, basi ina 1/2*200 = <<1/2*200=100>>100
Jumla ya nambari kwenye kadi zenye herufi W na X ni 200+100= <<200+100=300>>300.
Ikiwa kadi yenye herufi Y ina jumla ya nambari kwenye kadi zenye herufi W na X, basi jumla ya nambari kwenye kadi ni 300+300 =600.
Kwa kuwa kadi yenye herufi Z ina lebo ya 400, jumla ya nambari zilizowekwa kwenye kadi ni 600+400= 1000
