Question 515111: On the first four exams, your grades are 76, 96, 55, and 77. You ate hoping to earn a C in the course. This will occur if the average of your five exam grades is greater than or equal to 70 and less than 80. What range of grades on the fifth exam will result in earning a C?

76, 96, 55, and 77 added = 304
A 70 avg for 5 exams --> 350 points
An 80 avg --> 400 points
350 - 304 = 46 for a C
400 - 305 = 96 for a B
-----
To make a C --> 46 <= grade <96
