Answer: D) 111

Step-by-Step Explanation: In order to determine how many slices of sausage pizza were sold, you have to find out how many pepperoni and cheese pizza slices were sold as well. It says that 117 slices of pepperoni pizza were sold, so we don't have to figure that one out. To find the cheese pizza slices that were sold, you have to subtract 117-34 because it says how many more pepperoni slices were sold than the cheese ones. The cheese pizza slices that were sold are 83 slices. So, to find the sausage pizza slices that were sold, you're going to add 83 and 28, since the 28 more slices of sausage pizza was sold than the cheese. 83+28=111.
