Samuel made a 94, 88 and 63 on his history tests. He has one more history test that will be average to complete his final grade of an 88. What grade does Samuel need to make to be passing.
To find out what grade Samuel needs to make on his final history test in order to have an average grade of 88, we can use the following formula:
(94 + 88 + 63 + x) / 4 = 88
Solving for x (the grade he needs to make on his final test), we get:
(245 + x) / 4 = 88
245 + x = 352
x = 107
Therefore, Samuel needs to make a 107 on his final history test in order to have an average grade of 88 for the class. Since grades typically range from 0 to 100, Samuel will not be able to pass the class with the current grading system.
