Karen has a credit of $31.38 at ABC Store. Which number below best represents a Karen's credit?

A. - 21.38

B. 31.38

C. - 31.38

D. 21.38

B. 31.38

We can immediately rule out A and D, because we're looking at 31.38, not 21.38. And considering C, we can rule that out as well, because Karen has a credit of $31.38, which implies positive, or gain. If it were to be a negative, then she would have lost that amount of money.
