Answer:
Please see answers below.
Step-by-step explanation:
Annual demand rep D=11,800
Setting up cost rep S = $48
Holding cost per year rep H=$0.1
Production rate per year = Production facility × Capability of production
=300 × 95
=28,500
Therefore;
a. Optimal size of the production
Q = √2DS/H(1-D/P)
= √2×11,800×48/0.1(1-11,800/28,500)
=√11328000-0.5859649123
=√11328000.586
=$3,366
b. Average holding cost per year
=QH/2(1-D/P)
=3,366×0.1/2(1-3,366/28,500)
=168.3(0.8818947368)
=$148.42
C. Average set up cost
=D/Q × S
=11,800/3,366 × 48
=$168.27
D. Total cost per year = Average set up cost + Average holding cost per year + Cost to purchase 11,800 lights
= $148.42 + $168.27 + 11,800(0.95)
= $11,526.69
