Hi Guest!
Background
--x = + x
-+x = -x
+-x = -x
++x = x
Following these rules, let's simplify the answer options.
Simplifying
A. 35 + 7 - 5
B. 35 - 7 + 5
C. 35 - 7 - 5
D. 35 + 7 + 5
What is the question asking for?
The question is asking for how much she has left.
Spending means she's subtracting from the total.
Thus, our equation should be 35 - 7 - 5.
Answer
Looking at our answer choices, it's clear that C is the same as 35 - 7 - 5, meaning our final answer is C.
I hope this helped. :)))))
