<human>:  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.
<bot>: How many points does the card with the letter X have? ** If the card with the letter X has half the number the card with letter W has, it has 1/2*200= 100
How many points do cards with letters W and X have? ** Together, cards with letters W and X have tags that total 100+200 = <<100+200=300>>300.
How many points do cards with letters W, X, and Y have? ** If the card with the letter Y has the total of the numbers cards with letters, W and X have, then the total for cards with letters W, X, and Y is 300+300 = 600
How many points do cards with letters W, X, and Y have? ** Since the card with the letter Z has a tag of 200, the total of the numbers the tags have is 600+400= 1000
