This math topic focuses on calculating the percent change, specifically, the tip percentage added to a meal cost. Each problem provides a scenario in which a final total paid for a meal (including a tip) is compared against the original cost of the meal. Students must determine the percentage increase, or tip percentage, from provided multiple-choice answers. This topic is intended to build foundational skills in understanding and calculating percentages, particularly in real-world contexts such as dining and tipping.
