Question 735231: sam's first four exam grades were 94,73,72, and 80. What must his score on the last test be in order to have overall test average of 84? Answer by solver91311(24713) (Show Source):
Hint: If five scores have an average of 84, then the sum of the five scores must be 5 times 84. Another hint: "You can't get there from here" MIGHT be a valid answer to this question depending on the maximum possible score on the last test.
