Answer:

The answer is

→ <u><em>B.) 43 old math textbooks</em></u>

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.

$516 + 84 = 600$

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!
