Question

Tim answered all the questions on his math test but got 10 answers wrong. He received 4 points for every correct answer, and there was no penalty for wrong answers. His score was 76 points.

Write an equation to determine the total number of questions (q) on Tim's math test.

Answer 1

Since his score was 76 points and he received 4 points per correct answer, you can find the number of correct answers by dividing 76 by 4

76/4 = 19

The you add to that the number of questions he got wrong:

19 + 10 = q=29 total questions.
