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. :)))))
