Each pad of paper cost 3.25. Here is how I found it.
21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25
X = 3.25
Is this what you were looking for?
Answer:
C Side ZX
Because ZX is a reflection of CD
Expected value E(x) = 0.9994(150000 - 181) = 0.9994 x 149819 = $149,729.11
Not 100% sure but it might be B
Convert the fractions to decimals:
3/5=0.6
4/5=0.8
You have to find 2 fractions between these 2 numbers. You could pick anything.
7/10= 0.7 = less than 0.8 but greater than 0.6
75/100=0.75 = less than 0.8 but greater than 0.6
Hope this helps
