Book Sale Discount

Challenge: Jonny wants to purchase three books with prices of $15.08, $50.88, and $150.96. Each book comes with two coupon options, either $5 off or 5% off. The object of the activity is to create an algorithm that helps Jonny compare the discounts and determine the most cost-effective choice. Code the VR Robot to drive around the Art Canvas +playground to “click” the coupon buttons under each book to indicate which coupon to use and calculate the total cost of the three books using selected coupons. To “click” a button, use the VR Pen to fill the button area with green.
