[Creator : ]
Description
In the game, Deliv-e-droid, a robot droid has to deliver packages while avoiding obstacles. At the end of the game, the final score is calculated based on the following point system:
- Gain 50 points for every package delivered.
- Lose 10 points for every collision with an obstacle.
- Earn a bonus 500 points if the number of packages delivered is greater than the number of collisions with obstacles.
Your job is to determine the final score at the end of a game.
Input
The input will consist of two lines. The first line will contain a non-negative integer $P$, representing the number of packages delivered.
The second line will contain a non-negative integer $C$, representing the number of collisions with obstacles.
Output
The output will consist of a single integer $F$, representing the final score.
Sample 1 Input
5
2
Sample 1 Output
730
There are 5 packages delivered, so 5×50=250 points are gained. There are 2 collisions, so 2×10=20 points are lost. Since 5>2, a bonus 500 points are earned. Therefore, the final score is 250−20+500=730.
Sample 2 Input
0
10
Sample 2 Output
-100
There are 0 packages delivered, so 0×50=0 points are gained. There are 10 collisions, so 10×10=100 points are lost. Since 0≤10, no bonus points are earned. Therefore, the final score is 0−100+0=−100.
