My friend John likes to go to the cinema. He can choose between system A and system B.
```
System A : he buys a ticket (15 dollars) every time
System B : he buys a card (500 dollars) and a first ticket for 0.90 times the ticket price, 
then for each additional ticket he pays 0.90 times the price paid for the previous ticket.
```
#Example: 
If John goes to the cinema 3 times:
```
System A : 15 * 3 = 45
System B : 500 + 15 * 0.90 + (15 * 0.90) * 0.90 + (15 * 0.90 * 0.90) * 0.90 ( = 536.5849999999999, no rounding for each ticket)
```
John wants to know how many times he must go to the cinema so that the *final result* of System B, when rounded *up* to the next dollar, will be cheaper than System A.

The function `movie` has 3 parameters: `card` (price of the card), `ticket` (normal price of 
a ticket), `perc` (fraction of what he paid for the previous ticket) and returns the first `n` such that
```
ceil(price of System B) < price of System A.
```
More examples:
```
movie(500, 15, 0.9) should return 43 
    (with card the total price is 634, with tickets 645)
movie(100, 10, 0.95) should return 24 
    (with card the total price is 235, with tickets 240)
```
