the correct option is C.
"Her calculations are wrong because there should only be 0.5 inches of paper left over."
We know that the dimensions of the paper are 8.5 inches by 11 inches.
Now, she wants to cut it into 2 inch by 11 inch strips.
Now, notice that if you have 4 of these strips, the width will be:
W = 4*2in = 8in
If we subtract this to the original width, we get:
8.5in - 8in = 0.5in
So what she should got is 0.5 instead of 3, then we conclude that the correct option is C.
"Her calculations are wrong because there should only be 0.5 inches of paper left over."
