Answer:
The price of each CD before tax is $12.50.
Step-by-step explanation:
Given:
Lamar bought 3 CDs that were each the same price, including sales tax he paid a total of 40.20.
Of that total,2.70 was tax.
Now, to find the price of each CD before tax.
So, we reduce the tax from total:
Now, as given the price of each were same:
Therefore, the price of each CD before tax is $12.50.

B
Step-by-step explanation:
Answer:
PR = 5 because LP + PR = LR according to the Segment Addition Postulate, and 7 + 5 = 12 using substitution
Step-by-step explanation:
The naming of the segments suggests that point P is between L and R, so that ...
LP + PR = LR
This corresponds to the last choice.
_____
<em>Comments on the alternate interpretation</em>
On the other hand, if point L is between P and R, then the segments are PL and LR. The Segment Addition Postulate would tell you that ...
PL + LR = PR
The Reflexive Property of Congruence would tell you that PL = LP. The Substitution Property would tell you LP can be substituted into this equation, making it ...
LP + LR = PR
and by the commutative property, ...
LR + LP = PR.
Multiple properties of addition and congruence are involved with this interpretation, which more or less matches the third choice. That is, the simple explanation of answer choice 3, by itself, is insufficient to explain why the length of PR should be considered to be 19, not 5.
