Morgan wanted to make mashed potatoes. She bought a 4+pound bag of potatoes. Two-sixth of the bag was rotten and had to be thrown out. She then bought another bag that weighed two and a half pounds. How much mashed potatoes could she make?

A. 3 4/6

B. 101/6

C. 3 2/3

D. 6 1/6

2/6 = 1/3

1 - 1/3 = 2/3
so she had 4*2/3 = 8 /3 from the first bag
then add 2 1/2 which is 5/2
8/3 + 5/2 = 16/6 + 15/6 = 31/6 = 5 1/6 typo?
