Cost-Effectiveness in Consumer Arithmetic

In this video, Mr. V introduces consumer arithmetic by exploring cost-effectiveness in purchasing decisions. He compares two Lusca products by calculating their cost per gram to determine which is more economical. A similar analysis is conducted for Mini-Me drinks, comparing different sizes to find the best value. The video concludes with a call to action for students to practice these calculations on their own, emphasizing the real-world application of math skills.
