Answer:

Step-by-step explanation:
Linear function:
A linear function has the following format:

In which m is the slope and b is the q-intercept.
One week you charged $4 per guest and averaged 80 guests per night. The next week you charged $10 per guest and averaged 44 guests per night.
This means that we have these following points: (4,80), (10,44).
Finding the slope:
With a pair of points, the slope is given by the change in q divided by the change in p.
Change in q: 44 - 80 = -36
Change in p: 10 - 4 = 6
Slope: 
So

Finding b:
We replace one of the points. Replacing (4,80).



So

Answer:
b
Step-by-step explanation:
denominator(5) stays the same
multiply 2 by 4 since that is 1 fourth of an hour.
So now its 8/5
5 goes into 8 1 time with 3 leftover
So the 1 is a whole number now
the leftover fraction 3/5
=1 3/5
Answer:
divide this amount ($88.26875) by the number of people
Step-by-step explanation:
6.75% of $72.50 is 4.89375
15% of $72.50 is 10.875
72.50 + 4.89375 + 10.875 = 88.26875
divide this amount (88.26875) by the number of people
Answer:
35.7 / 0.07 = 510
