A and C

janu16 · Answer

A. is 10 - (1/4 * 10) or we could write that as 10(1 - 1/4) or we could then say 
10* 3/4  or 3/4 * 10  That is the same as C.  A. and C. are the same value.

Furthermore choice B is saying she is watching more TV than she was.  That has gotta be wrong.

so appears there are two correct answers.
