8. (6pts) Jane is buying candy to take to the movies with a friend. Her friend is very picky and always gets a specific mixture of Reese's peanut butter cups and gummy bears. Janee remembers that the last time they went to the movies her friend bought 15 ounces of candy and paid $9.00. If Reese's cost 75 cents per ounce and gummy bears cost 50 cents per ounce, how much of each candy should Jane purchase for her friend? (Remember to define all variables and give your answer in a complete sentence with appropriate units.)
