4: (A.8)(A) 8. A bake sale sold pies for $8 each and cookies for $1 each. Total sales for these items were $108. Ten times as many cookies were sold as pies. Which system of equations can be used to find the number of pies, p, and cookies, c, sold? F G 10p = c 8p + c = 108 H J p = 10c 8p = 108 – c c = 108 – 8p 8p + c = 108 10p = c p + 8c = 108 Page 8
