[Free] Your task: 1. Let \( n \) represent the number in step 1 and show what happens through step 6. - Step 1: Pick a number \( n \). - Step 2: Double it. Result: \( 2n \). - Step 3: Add 5. Result: \( 2n + 5 \). - Step 4: Multiply by 50. Result: \( 50(2n + 5) = 100n + 250 \). - Step 5: If you've had your birthday this year, add 1764; if not, add 1763. - Result if birthday has passed: \( 100n + 250 + 1764 = 100n + 2014 \). - Result if birthday has not passed: \( 100n + 250 + 1763 = 100n + 2013 \). - Step 6: Subtract the year of your birth. 2. Explain why the result is always the original number followed by your age. - After step 6, the number becomes \( 100n + (current \ year - birth \ year) \). - The expression \( current \ year - birth \ year \) gives your age, so the result is \( 100n \) (which shows the original number) followed by your age.
