This mathematical exercise asks the reader to follow a series of steps: pick a number for how many times they want to eat out each week, multiply by 2 and add 5, multiply by 50, then add either 1751 or 1750 depending on if their birthday has passed this year, and subtract the year they were born. The result is a 3 digit number where the first digit represents how many times they want to eat out each week, and the last two digits represent their age.
