Each machine at a certain factory can produce 90 units per hour. The setup cost is 20 dollars for each machine and the operating
sasho [114]

Answer:

a)  Total Cost=20n+\frac{(\frac{40000}{90}*26)}{n}

b)  n=24

Step-by-step explanation:

From the question we are told that:

Rate r=90 units per hour

Setup cost =20

Operating Cost =26

Units=40000

Generally the equation for Total cost is mathematically given by

Total Cost=20n+\frac{(\frac{40000}{90}*26)}{n}

T_n=20n+\frac{11556}{n}\\\\T_n=\frac{20n^2+11556}{n}.....equ 1

Differentiating

T_n'=\frac{n(40n)-(40n^2+11556)}{n_2}\\\\T_n'=\frac{20n^2-11556}{n^2}.....equ 2

Equating equ 1 to zero

0=\frac{20n^2+11556}{n}

n=24

Therefore

Substituting n

For Equ 1

T_n=\frac{20(24)^2+11556}{24}

F(n)>0  

For Equ 2

T_n'=\frac{20(24)^2-11556}{24^2}

F(n)'<0
