Answer:
B
Step-by-step explanation:
So we have the equation:
Where c represents the wedding cost and n represents the number of people who attended the wedding.
We know that the wedding cost a total of $8625. Thus, we can plug this number in for c and solve for n:
Subtract 1500 from both sides. The right cancels:
Now divide both sides by 75:
Thus, a total of 95 people attended the wedding.

Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x ----> the time in hours
y ----> the distance in miles
<em>Find the value of k</em>
For the point (4,2268)
The slope represent the speed of the airplane
so
The linear equation is
Part 1 :
The point (0,0) represents the starting point of the aircraft, when the time and distance are equal to zero. The cruising starts when time t = 0.
Part 2 :
The point (4, 2268) represents the plane after 4 hours of cruise , and shows it has traveled a distance of 2268 miles after 4 hours
