Question

Are these all OK?
What do you figure the score will be? (a soccer game etc.)
  How much do you figure it's worth?    (shopping)
  How long do you figure it will take?    (going somewhere)
  How much do you figure it would cost?  (restoration)

Answer

They sound fine except the first just doesn't sound right. More like what do you think the score will be. Figure isn't really wrong but just a bit odd here.

Answer

They all seem fine to me.
