What is the value of p? 1) A customer who buys 2 loaves is charged 10 percent less per loaf than a customer who buys a single loaf. 2) A customer who buys 6 loaves of bread is charged 10 dollars. Statement 1: Since one loaf costs$p and each additional loaf costs $q, the cost per loaf when 2 loaves are purchased = (p+q)/2. This value is equal to 10% less than p. In other words, (p+q)/2 is equal to 90% of p: (p+q)/2 = .9p p+q = 1.8p q = .8p. No way to solve for p. INSUFFICIENT. Statement 2: Since one loaf costs$p and each additional loaf costs $q, the cost for 6 loaves = p + 5q. Thus: p + 5q = 10. No way to solve for p. INSUFFICIENT.
