1. The Soft Toys Company has collected information on fixed and variable costs for four potential plant locations.
Location | Annual Fixed Cost | Unit Variable Cost |
A B C D | $200,000 $300,000 $400,000 $600,000 | $70 $65 $45 $40 |
a. Plot the total cost curves for the four plant locations on a
single graph (Use Excel or hand-drawing).
Hint: You can start with different Q (output quantity) such as 0,
5000, 10000, 15000, etc. and record responding total costs of each
location. Accordingly, you can draw a line of each location on
Excel worksheet (hand-drawing is fine) while X-axis is Q and Y axis
is total cost.
b. Compute the range of demand for which location has the best cost advantage (the least total cost).
c. Which plant location is best if demand is 30,000 units?
b) Between A and B
200000+x*70= 300000+x*65
5x= 100000
x= 20000
Between B and C
300000+65x= 400000+45x
x= 5000
Between An and C similarly
x= 8000
Between A and D
200000+x*70= 600000+40x
x= 13333.33
Between B and D
300000+65x=600000+40x
x= 12000
A is better when x<= 8000
C is better til 40000(From C and D)
8000<=C<= 40000
D is better x>= 40000
c) When the quantity is 30000
As it falls under C range i.e. >=8000 and <=40000
C is better option
