Answer:
C!
Explanation:
Three friends AND You are eating a pizza with 12 slices. This means 4 people will be eating the same number of pizza slices. Therefore, 4 friends eat x amount of pizza slices, which equals 12 slices, or one whole pizza. So, 4x=12. If you wanted to solve for x, (the number of slices each person eats) you just divide 4 by 4x and then divide 12 by 4. You will get 3. So three slices per person. Hope this helped!
