Quizplus · Accepted Answer

Let x be the number of flashlights sold. Then the number of pens sold would be 7x (since customers bought 7 times as many pens as flashlights). The total sales can be represented by the equation 10x + 6(7x) = 624. Simplifying this equation yields 52x = 624, which gives x = 12. Therefore, the number of pens sold would be 7x = 84. So the best choice is C.
