Test scores, 75,63,68 what does he need for a (c )grade?

You're going for the average here. This is how you set this one up.


Assuming a C is 70 and above:


(75+63+68+x)/4=70


(206+x)/4=70


206+x=280


x=74

Reply:That all depends on what constitutes a C. In some schools, 70 is a C; in other schools, 76 is the lowest value in the C range.





Presuming 70 is a C, 4x70=280. The two lowest scores lack a total of 9 points for them to be at 70. The highest grade is 5 points over 70. 9-5=4.





The student would have to earn at least a 74 on the fourth assignment.
