Aswered :

She started with 10 points - In the first round she lost 20 points + In the second round she won 45 points

Answer 2

A.

Explanation:

It's set up exactly as it is said. She starts with 10 points automatically so you would put:

10

Then it says that she lost 20 points. Losing is subtraction. You would add this to the equation:

10-20

Then it says she won 45 points. Winning is addition. You would add this to the equation:

10-20+45

This equation matches up with A. thus A. being the correct answer. If they ask for the answer, it is 35 by the way. Hope this helps!
