Meg scored 45, 48, and 56 points on three tests. how many points should she get on the fourth test to get an average score of 60?
49.67 points
52.25 points
91 points
93 points

She should get 91 scores.

Step-by-step explanation:

Let x be the score meg get on fourth test,

Given,

She scored 45, 48, and 56 points on three tests.

Thus, the total sum of the scores in four test = 45 + 48 + 56 + x

= 149 + x

Also, the number of tests = 4,

According to the question,

   ( By Cross multiplication )

              ( Subtracting 149 on both sides )

Hence, she should get 91 scores on the fourth test to get an average score of 60.

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
