The owners of a car wash want to increase their revenue. They decide to reduce their price by $6.00. Currently they charge $10.99 for the Deluxe Super Wax Car Wash. In a typical week they sell 70 Deluxe Super Wax Car Washes. They know from previous experience that a $6.00 price drop will increase the average to 110 Deluxe Super Wax Car Washes a week. Each wash costs them $1.99 in chemicals, water, and labour. What percentage must their sales increase by to maintain their current Total Contribution? Dropping their price $6.00 too much? 200% and $6 is too much 286% and $6 is too much 28.6% and $6 is not too much 28.6% and $6 is too much None of these are correct or cannot be determined
