Mom28kds Posted April 25, 2011 Share Posted April 25, 2011 The answer keys are $32 for all 10 LU and the TM are $14 for all LU's. Why is that. I was going to place my order and noticed this. It didn't make sense to me and thought I'd ask those of you who use this first. I'm getting: Math 400 Math 100 LA 300 LA 100 Quote Link to comment Share on other sites More sharing options...
i.love.lucy Posted April 25, 2011 Share Posted April 25, 2011 But the TM has the answers, so you don't need the keys. I think it's because often people buy LUs as individual units and you might want just the key for LU 307 for example. All you need are the LUs and the TM.
