Math Trick

Try solving this using algebra. :)

1. First of all, pick the number of times in a week that you would like to go out to eat. (a number more than 1 but less than 10)
2. Multiply this number by 2.
3. Add 5.
4. Multiply it by 50.
5. If you have already had your birthday this year add 1758. If you haven't, add 1757.
6. Now subtract the 4-digit year that you were born in. You should have a three digit number.

The first digit of this was your original number. (I.e., how many times you want to go out to eat in a week.)

The next two numbers are YOUR AGE !

THIS IS THE ONLY YEAR (2008) IT WILL EVER WORK!
