First we write the variables already defined: m = the number of magazine subscriptions sold n = the number of newspaper subscriptions sold We now write the system of inequations based on the following facts: "he earns $ 23 for each magazine subscription and $ 54 for each newspaper subscription that he sells. his goal is to make more than $ 642 per week" 23m + 54n> 642 "I have expectations to sell at least 10 subscriptions per week" m + n> = 10 Answer: A system of inequalities that models the given situation is: 23m + 54n> 642 m + n> = 10
