Last weekend, Transformers 2 dropped down to 15th place at the box office — don’t feel bad, it’s still the #1 movie of the year by a margin of over $100 million dollars — with $1.6 million.  That raised its overall U.S. gross to $396.75 million.

Will it be able to break the $400 million mark?

Probably, but it’ll be close.  Transformers 2 has been dropping at an average of 40% each weekend.  During the Monday-Thursday period we’re in right now, it’ll make about $700K total, so if it makes $960K over the Friday-Sunday periods — a 40% drop from $1.6 million — it’ll finish the weekend with a new total of $398.35 million.  If it drops another 40% over the following week, it’ll make another million bucks, raising the total to $399.35.

And from there it can climb past the $400 million mark, right?  Depending on how fast it loses the theaters its playing in, it should have another $2-3 million in it or so, finishing out with around $402 million.  We’ll see how close I am to being correct, though.

I totally just outed myself as a math geek, didn’t I?
