Answer:
A. 2r (and each person gets 4 slices)
Step-by-step explanation:
By seeing how many times you can put 7 into 30 you can determine the number of slices each person will get.
7 x 2 = 14, you can still fit 7 more into this without going over 30
7 x 3 = 21, you can still fit 7 more into this without going over 30
7 x 4 = 28, you can't fit 7 into this anymore
30-28=2, remainder 2
