Question

Tennis balls are filled with nitrogen gas. 1.7% of nitrogen gas has escaped from a particular ball after 10 hits. a) How much gas is left after a game that had 23 hits on the ball?

Kay this is what I did: my equation is f(x)=100(0.983)^(x/10), and then I subbed 23 into x. I got 96%. Is this right?
