Solution of the inequality
The options are not properly presented. However, I'll solve the question without considering the options.
To simplify the given inequality, it's worth knowing that the absolute function of any inequality returns the positive form of any value it takes (whether negative or positive).
Since, we've understood that the absolute can take negative of positive, the above inequality can take the following form
-3 < X - 4 < 3
Add 4 through
4 - 3 < X - 4 + 4 < 3 + 4
1 < X < 7.
Hence, |X - 4| < 3 is equivalent to 1 < X < 7.

Answer:
Amount of money raised for 875 people=A=$21,875
Step-by-step explanation:
This can be expression in the equation, A=k.N;
Where;
A=Amount of money raised=$2500
k=Constant of proportionality(Amount of money per attendee)
N=Number of attendees=100
Replacing in the expression;
Amount of money raised=K×Number of people who attend
2500=K×100
K=(2500/100)=25
Amount of money per attendee=K=$25 per attendee
How much money was raised for 875 people?
Using the expression, A=k.N
where;
Number of people (N)=875
k=25
Replacing;
A=(25×875)=$21,875
Amount of money raised for 875 people=A=$21,875
C) Infinitely many solutions.
any real number you put as (x) will give you a different input on both playing fields of these two Linear functions.
You can put 4(1)+ 3 = 7 You can do 4(-1) + 3 = -1
every new input gives you a new output. This would also mean these two are also functions, fun fact.
