Answer:
Explanation:
Let the number of days per year that the company will need the equipment in order to justify its purchase b represented by x.
Based on the information given, this will then be:
1130x + 180x = 199000(A/P, 10%,10) - 65000(A/F, 10%, 10), + 32000 + 220x
1310x = 199000(0.1627) - 65000(0.0627) + 32000 + 20x
1310x - 20x = 32377.3 - 4075.5 + 32000
1290x = 60301.8
x = 60301.8/1290
x = 46.75
Therefore, the answer is 46.75 days.

Incomplete question
Complete question:
An aircraft factory manufactures airplane engines. The unite cost C ( the cost in dollars to make each airplane engine) depends on the number of engines made. If x is the number of engines made, then the unit cost is given by the function C(x)=0.8x^2-160x+26848. What is the minimum unit cost? not rounded
Answer: $18848
Explanation:
Since we have the function
C(x) = 0.8x²-160x+26,848
Firstly, we differentiate
C'(x) = 1.6x - 160
The minimum cost will occur where x = 100.
The vertex of a parabola (quadratic equation) occurs where X = -b/2a, in this case we have that
X = 160/(2×0.8) = 100
Therefore, we substitute x = 100 into the original equation
We have that
C(x) = 0.8(100)²-160(100)+26848
C(x) = 8000-16000+26848
C(x) = $18848

Top-down planning
Explanation:
Top-down planning -
It refers to the method planning , where the goals are bifurcated and placed according to the hierarchy from top to bottom , is referred to as top - down planning .
As breaking and arranging the goals , make the process to accomplish the goals in a better manner .
The process require the movement from higher level to lower level , in a very orderly manner to hasten the process .
Hence , from the given scenario of the question ,
The correct answer is Top-down planning .
