Answer:

a) To earn C he needs at least 68 and less than 98

b) No, he couldn't make it.

Step-by-step explanation:

I. His avg value is (382 + x)/6

 I pick a random number and that gave

 (68 => to reach 75) and (98 => to reach 80)  

So that makes he needs at least 68 and less than 98

II. The reason why he cannot make it is

 if 100 is 100%

      =   (100 + 382)/6

      = 80.33 That's impossible to reach 90

Hope that help :)
