Pay attention in class then..
Answer:
10 or 1000 in hundreds of units
Step-by-step explanation:
Given the supply curve of portable radio rentals:

and the demand curve for portable radio rentals:

we need to find the equilibrium of these two curves ( replace either's right hand side on the other's left hand side)
we have:

solving we have
or
in hundreds of units
Now the noise is equal to 3, therefore, we have to find the social supply curve by adding 3 to the first supply curve. following:

We find the intersection bewteen the social supply curve and the demand curve ( social equilibrium rental ):

Which gives
or
in hundreds of units.
Now that we integrated the noise into our considerations, the equilibrium rental exceeds the social equilibrium rental by 10 (50-40) (1000 in hundreds of units)
Oh my gosh...thats a lot. Umm, well let's start with what the equation says. This will break it down to where it's of better understanding. What is the equation asking you to do? You have heard of the acronym "PEMDAS", correct? (Parantheses, Exponents, Multiplication, Division, Addition and Subtraction) Follow that order of operations and see what it is the equation wants done first. Solve it, basically...then we will focus on the actual question parts.

Answer:
A.28
Step-by-step explanation:
Substitute a with 28 so:
-6+28=22
Then simplify the equation:
22=22
