📖 Percentage: The Language of Comparison

Saving $10 on a $20 item feels significantly different than saving $10 on a $200 item, even though the amount is the same.

💡 The 15% Shortcut
Want to calculate a 15% tip without a calculator? First, find 10% (move the decimal one place to the left). Then, take half of that (5%) and add them together. Example: 10% of $40 is $4.00, 5% is $2.00. Total = $6.00.
