5. An actuary works for an auto insurance company whose customers all have insured at least one car. She discovers that of all the customers who insure more than one car, 70% of them insure at least one SUV. Furthermore, she observes that 47% of all the customers insure at least one SUV. If 65% of all customers insure more than one car, what percentage of the customers insure exactly one non-SUV?
