The answer is
→ B.) 43 old math textbooks
Step-by-step explanation:
How did I get the answer?
Well, I multiplied 12 by 43. Which is $516 dollars sold from old math textbooks. Then I multiplied 3 by 28. Which resulted is $84 dollars sold from paperback novels.
Add them together.
What I typed in using a calculator:
(12 x 43) + (3 x 28) = 600
Therefore, 43 old math textbooks sold this year.
Hope this helped!
