We are to find the average rate of change between n=3 and n=4 for the given function.
Average rate of change =

So the average rate of change for the given function from n = 3 to n = 4 is 6
Answer:
y=4
x=-1
Step-by-step explanation:
replace y
2x+6=-x+3
3x=-3
x=-1
y=2x+6
y=2(-1)+6
y=-2+6
y=4
To find the cost per one pound, we divide the total cost $222.50 by the total number of pounds (50 lb).
