Attached you can find the graph obtained with a graphing utility.
I included only the region where the solution is.
I marked with dotted lines the minimum point and used arrows to indicate its components.
a) the minimum average cost is obtained when you produce 9 riding lawn mowers.
You can check it if you use the formula with three values of x: x =8, x = 9 and x = 10.
Answer: 9
That coordinate is indicated with an arrow.
b) The minimum average cost is obtained when you use the formula for the average cost with x = 9:
C(x) = 0.5*(9)^2 + 23(9) - 216 + 2600/x = 320.39
Answer: 320.39

Answer:
3 multiplied by 1.5 equals 4.5
Step-by-step explanation:
3*x= 4.5 We can do division
3x/3 = 4.5/3
x = 1.5
3 multiplied by 1.5 equals 4.5
Hope this helps!
Answer:
Step-by-step explanation:
Given that Audra was drawing a perpendicular bisector of segment AB with a compass. She started with line segment AB. Then, she placed her compass point on A and opened the compass more halfway to B.
Her next step will be "Using the width of the compass from the previous step, draw two arcs to the left and right of both A and B".
