Quizplus · Accepted Answer

Let x be the number of hot water bottles sold. Since customers bought 10 times as many thermometers as hot water bottles, the number of thermometers sold would be 10x. The total sales equation can be written as 2(10x) + 6x = 312. Simplifying the equation gives 26x = 312, which means x = 12. Therefore, the number of hot water bottles sold is 12.
