You have two restrictions. A restriction of hours, and a quantity restriction. Let's call:x represent the number of hats made. y represent the number of scarves made. For the restriction of hours we have that the inequality is:12x + 6y≤20For the restriction of quantity the inequalities are:y≤8x≤5Therefore, the restrictions that best represent the problem are: 12x + 6y≤20y≤8x≤5
