Answer:
1006.72
Step-by-step explanation:
Multiply 9.68 by 104
It's the last choice. In the top row you have the 1's that are the coefficients on the x and the y, and the solution for that equation is 21; in the second row you have the 5 from the x and the 4 from the y and the solution for that equation which is 20. I'm more used to writing them down instead of across, but there you have it anyways
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
