Three girls searched for geodes in the desert Corinne collected 11 1/8 pounds Allen collected for 5 8 pounds and Leandra collected 3 3/4 pounds how much more did Corinne collect than the other two girls combined? A 2 1/2 pounds B 2 3/4 pounds C 2 7/8 D3 3/4?

Corine collected a total of 11 1/8 pounds of geodes.

Allen collected 5 1/8 pounds of geodes.

Leandra collected 3 3/4 pounds of geodes.

X = Allen + Leandra

X = 9/8 + 3 3/4

X = 9/8 + 15/4

X = (9 + 45) / 8

X = 54/8 = 2 2/8

= 11 1/8 - 8 2/8

= 10 9/8 - 8 2/8

= 2 7/8

So the answer is letter C. 2 7/8
