Calculating Discounts and Percentages

This video from MooMooMath explains how to calculate discounted prices using a formula. It provides three example problems: calculating the discounted price of a $55 shirt marked down by 15%, a $45 watch marked down by 10%, and determining the original price of a shirt with a discounted price of $30 after a 20% markdown. The video also introduces a shortcut method for these calculations. The tutorial concludes with a brief channel promotion.
