Wibs and Wobs
Let's say 26 zips weigh as much as 4 crids and 2 wobs. Also, 8 zips and 2 crids have the same weight as 2 wobs.

7 zips weigh as much as a single wob
ReplyDeleteThat was my answer, too, Abe.
ReplyDelete1) 26Z=4C+2W
2) 8Z + 2C = 2W
Take 2 and rearrange to get
4C=4W-16Z
Take that and put it into 1)
26Z = 4W - 16Z + 2W
42Z = 6W
7Z = W
