Answer:

$12

Step-by-step explanation:

If you're taking off 25% of the regular cost, "taking off" means subtracting. So if we subtract 25% OF 16, the word "of" means to multiply here. So our expression then becomes:

16 - .25(16)

16 - 4 = 12

So the CD will sell for $12.

Luba_88 [7]

The z-score of the information given is:
z=(x-μ)/σ
where
μ-mean
σ- standard deviation

from the information given:
x=93.02
μ=89
σ=√625=25
hence
z=(93.02-89)/25
z=0.1608
thus
P(X≥x)=1-0.5636=0.4364=43.64%
