Answer: Choice B</h3>
Doug borrowed $2 from his friend every day from Monday through Friday. How much money does Doug owe in all?
==============================================================
Explanation:
The notation 5(-2) is the same as saying "5 times negative 2"
The negative represents the amount of debt that Doug goes into when borrowing that $2. When borrowing the same amount over the course of 5 days, he'll be in debt a total of 10 dollars. So we'd write -10 to represent this.
You could also write it out the longer way
-2 + (-2) + (-2) + (-2) + (-2) = -10
There are five copies of "-2" being added up to arrive at -10
Though it's much simpler to say
5(-2) = -10
