Graph the 2 inequality. identify a solution how many bracelets and earring can he sell. SOLUTION first thing get all important info braclet cost 2 bucks earring cost 3 bucks needs to make 500 secondly identify the variables, you know how much the stuff cost but you dont know how many of each he needs to sell X = the number of bracelets Y is the number of earings, write inequality represent the income from the jewrly sold 2x+3y>500 next you need to know that he will sell more than 50 braclets write an inequality to represent this x>50. Not sure how to graph it though sorry
