SOMEONE HELP ME PLEASEEE !!

Answer 1

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

b) No, he couldn't make it.

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 :)
