-------------------
A linear function has the following format:
In which
- m is the slope, that is, the rate of change.
- b is the y-intercept, that is, the value of y when x = 0.
In this problem:
- Fixed cost of $9 per month,
.
- Cost of $2 for each delivery, thus

Answer:
21, 17, 13
Step-by-step explanation:
Find the mean of the 2 given values
mean = =
= 17
Noe find the mean of 25 and 17 and 17 and 9
mean = =
= 21 and
mean = =
= 13
Thus the 3 means are 21, 17 and 13, that is
25, 21, 17, 13, 9
