Answer: a) below 27,500 units Dallas is best. Above, Detroit is best.
b) below 20,500 units Dallas is best. Above, Detroit is best.
Step-by-step explanation:
To calculate we shall be using the Point of Indifference Value.
Now, let's borrow x from Algebra and denote it as the Quantity (Q) where the cost of the 2 processes are equal..
a) Total cost = Fixed Costs + ( Variable cost * Q)
Dallas Total Cost = 560,000 + 30x
Detroit Total Cost = 780,000 + 22x
Equating them we get,
560,000 + 30x = 780,000 + 22x
8x = 220,000
x = 27,500 units.
Below 27,500 radio units then Dallas would be preferable due to lower fixed costs. Above 27,500 radio though then Detroit would be better due to lower Variable costs.
b) Dallas costs rise by 10%
= 560,000(1 + 0.1)
= $616,000 is their new cost.
Using the same methodology as A above we say,
616,000 + 30x = 780,000 + 22x
8x = 164,000
x = 20,500 units.
Below 20,500 radio units then Dallas would be preferable due to lower fixed costs. Above 20,500 radio though then Detroit would be better due to lower Variable costs.
