a. a 3 ounce box (which adults will buy) sold for 48 cents; a 4 ounce box (which children will buy) sold for $1.12. b. a 3 ounce box (which adults will buy) sold for 48 cents; a 4 ounce box (which children will buy) sold for 64 cents. c. a 2 ounce box (which adults will buy) sold for 36 cents; a 4 ounce box (which children will buy) sold for 76 cents. d.
