Vanessa ha scored 45 32 and 37 on her 3 math quizzes. she will take one moe quiz and wants a average of at least 49. what is the minimum score vanessa needs to earn on her fourth quiz

In this question, Vanessa is doing 3 math quizzes and then doing 1 more which makes a total 4 test. She wants to get 49 average scores, so the total score she needs to have should be: 4*49 = 196 scores.

Then the next score that Vanessa should get in her 4th score:

Total score = score1 + score2 + score3 + score2

196 = 45 + 32 + 37 + score4

196 = 114 + score 4

score 4 = 196 - 114 = 82

I think the answer is 46.
