On a math quiz, Mary scored 3 points for each of the 12 multiple choice questions she answered correctly, and 5 points for each of the 8 free response questions she answered correctly. What was the total number of points Mary scored?

(3 * 12) + (5 * 8) = ?

3(12)+5(8) = ?? Can you finish from here?

Yes. I didn't know I was to assume that she answered all 20 questions correctly. Thank you!

You're welcome?

To find the total number of points Mary scored, we need to calculate the scores for both the multiple-choice questions and the free response questions separately, and then add them together.

For the multiple-choice questions:
Mary scored 3 points for each of the 12 multiple-choice questions she answered correctly. So the total number of points for the multiple-choice questions is 3 x 12 = <<3*12=36>>36.

For the free response questions:
Mary scored 5 points for each of the 8 free response questions she answered correctly. So the total number of points for the free response questions is 5 x 8 = <<5*8=40>>40.

To find the total number of points, we add the scores for the multiple-choice questions and the free response questions: 36 + 40 = <<36+40=76>>76.

Therefore, Mary scored a total of 76 points on the math quiz.
