Let us assume that cost of each granola bar be $x and that of a cup of yogurt be $y From person A's purchase, we get 12x + 7y = 15.5; equation A And from person B's purchase, 6x + 11y = 11.5; equation B Let us multiply equation B by 2 and subtracting equation A from it, we will get 12x + 22y - 12x - 7y = 23 - 15.5, => 15y = 7.5 or, y = 0.5 Substituting value of y in equation A, we can find x 12x + 7*0.5 = 15.5 => x = (15.5 - 3.5)/12 or, x = 1 Therefore, cost of granola bar is $1, and that of yogurt is $0.5
