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
3.2
Step-by-step explanation:
The Image attached below.
The given fraction is 
.
Step 1: Write the numerator inside.and denominator outside.
Step 2: If we multiply a number 5 by 3 we get 15. Write 3 in the quotient place.
Step 3: Now subtract 15 from 16, we get 1
Step 4: Place a decimal point after 3 and give one zero after 1, we get 10.
Step 5: Now multiply 5 by 2, we get 10.
Step 6: Subtract 10 from 10, the remainder is 0.
Step 7: The decimal is 3.2.
To answer this you can use proportions.
4 1/2 6%
------- = ----
X 100%
So, 6/4.5=1.3333...
Finally, 100/1.3333... appeoximately gives you 75.
75 hours are needed to restore the boat.
Hope this helped!
