if A is the midpoint of line segment PR, PA= 7x-11, and PR= 8x+14, then what is the value of line segment AR?

PA+AR=PR

AR= PR- PA

AR= 8x+14-(7x-11)

AR= 8x+14-7x+11

AR= x+25

Now, if A is midpoint of PR, then

PA=AR

7x-11= x+25

6x=36

x=6

Put value of x in AR

AR= 6+25= 31

Hope this will help:)

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
