Answer:
Width of the garden = 22.8 foot
Step-by-step explanation:
Area of the rectangular garden = 2077 square feet.
Let
Width of the garden = x
Length of the garden = 4x
Area of a rectangular garden = length × width
2077 = 4x * x
2077 = 4x²
x² = 2077/4
x² = 519.25
find the square root of both sides
x = √519.25
x = 22.787057730211
To the nearest tenth of a foot.
x = 22.8 foot
Width of the garden = 22.8 foot

Answer:
The number of watches must he repair to have the lowest cost is 54.
Step-by-step explanation:
The cost of operating Bob's shop is given by
Differentiate the given function with respect to x.
... (1)
Equate C'(x) equal to 0, to find the critical point.
Divide both sides by 4.
Differentiate C'(x) with respect to x.
C''(x)>0, it means the cost of operating is minimum at x=54.
Therefore the number of watches must he repair to have the lowest cost is 54.
