Elsie bought a video game for $85.00. If the store charges 170% of its cost for the game, how much is the store’s profit?

The store charges 170% or 170/100 x $85.00 = $<<170/100*85=144.50>>144.50.

Therefore, the store's profit is $144.50 - $85.00 = $<<144.50-85=59.50>>59.50. Answer: \boxed{59.50}.
