The best way to arrange the salon to best use what he has is:
- Place the bulb in the middle of the wall
- Directly face the chair and mirror in front of the bulb for proper lighting and reflection
- Place the chairs side by side of each other
- Each mirror should be facing each chai
This refers to the change in direction of a wavefront between two different media so that the wavefront returns to its originating medium.
Hence, we can see that from our knowledge of shadows and reflection, we can note that mirrors reflect and light helps to bring detail in a dark area and the chairs should be facing the mirrors directly so the customer can see his hair and how it is being cut by the barber.

Answer:
Explanation:
The first image that I attached to this solution is the diagram of a truth table for an 8 to 3 bit encoder.
The second image gives a sketch of the schematic.
The Boolean expression for the priority encoder including its zero inputs is defined in the third image attached.
Below is a snippet of the code for an 8 to 3 bit Priority encoder:
library IEEE;
use IEEE.STD_LOGIC_1164.all;
entity encoder8_3 is
port(
din : in STD_LOGIC_VECTOR(7 downto 0);
dout : out STD_LOGIC_VECTOR(2 downto 0)
);
end encoder8_3;
architecture encoder8_3_arc of encoder8_3 is
begin
dout <= "000" when (din="10000000") else
"001" when (din="01000000") else
"010" when (din="00100000") else
"011" when (din="00010000") else
"100" when (din="00001000") else
"101" when (din="00000100") else
"110" when (din="00000010") else
"111";
end encoder8_3_arc;
