To establish this equation we first need to assign some variables.
Let us assign x as the number of hours he has worked
and assign y as the total amount of money that he has earned
Therefore the equation y=36.50x is the equation that correctly represents how much money he makes regardless of how many hours he works. Just plug in how many hours you want for x and then solve the equation and you will get how much money he makes in x amount of hours. This is also proportional because for every hour that he works he gets the same salary of 36.50. It is proportional because no matter how many hours he works the salary will go up the same amount for each extra hour he works. The proportion is 36.50 dollars per hour worked.
P-4(p-2(3-p))=12 remove the parentheses
P-4(p-6+2p)=12 collect like terms
P-4(3p-6)=12 remove the parentheses
P-12p+24=12 collect like terms
-11p+24=12 move the constant to the right
-11p=12-24 calculate
-11p=-12 divide both sides
P=12/11
Alternative form
P=1 1/11
