Question

A student in an algebra course has test scores of 78, 88, 73, and 83. What score on the next test will raise the student's average to 82?

Answer 1

Answer:

88

Step-by-step explanation:

Let x be the score to be raised

avg of all =

(78 + 88 + 73 + 83 + x) / 5 = 82

=> 322 + x = 82 x 5

322 + x = 410

x = 410 - 322

x = 88
