Answer:
W = (h-kn-1)/2
Step-by-step explanation:
h - 2W = kn +1
Subtract h from each side
h - 2W-h = kn +1-h
-2W = kn +1-h
Divide each side by -2
-2W/-2 = (kn+1-h)/-2
W = (h-kn-1)/2
To find how many people 60% is you need to do 0.60 × 220 = 132
Now you know that 60% of 220 is 132.
Then subtract 132 from 220
220 - 132 = 88
The answer is 88
78+92=170
170/2=85
his current average is 85% so id go with C knowing that if his next quiz he got at least a 70, his average would be 80%
