Answer:
A) 0.75c
Explanation:
~The minuend of this expression is c, the subtrahend is 0.25c~
Let's pretend that "c" is anything, let's say they are cookies.
In the expression, you are taking 0.75 "cookies" away from the 1 "cookie"
So, it is just a simple subtraction problem! Now, solve that equation...
1cookie - 0.25 cookies = 0.75 cookies
or... 1c-0.25=0.75c
I hope this helps!
