Since I have no bankable knowledge on warrants, is my assumption correct in the math for warrants?

Let's take K as an example. I buy one "C" warrant for say $3 and strike is $32. Is it a correct assumption that after $35 and there is still time left, the profit starts? At $40 I have made $8 per, $50 - an $18 profit per?

Do these warrants sell only in blocks of 100 like the commons?
