This product is an interactive digital Google Sheets document. It includes 8 percent problems covering tax, tip, mark-up, and discounts on a colorful, Google Sheet. Students will determine the percent paid (if the discount is 25%, the amount paid is 75%), show their work in a percent proportion or equation, and calculate the total cost. Correct answers turn blue and wrong answers turn red. Students love the immediate feedback and teachers love that it's self-checking! Follow me on Instagram!
