Final answer:
The crossover point in units for California Gardens, Inc. to be indifferent between using the new Hi-Speed shredder and the old Clunker is 147,500 bags. This is calculated by setting the total costs of both shredders equal to each other and solving for the quantity of bags produced.
Step-by-step explanation:
To find the crossover point in units for the processes, we set the total costs of both machines equal to each other. The total cost for each shredder consists of the fixed cost plus variable costs, which depend on the number of units produced. For the Hi-Speed shredder, the total cost is $89,000 (fixed cost) plus $1.25 per bag (variable cost). For Clunker, it's $30,000 (fixed cost) plus $1.65 per bag (variable cost).
So the equation to find the number of bags (let's call it X) at which both shredders have the same total cost is:
89,000 + 1.25X = 30,000 + 1.65X
Solving for X gives us:
X = (89,000 - 30,000) / (1.65 - 1.25)
X = 59,000 / 0.40
X = 147,500 bags
Therefore, the crossover point is 147,500 bags. At this level of production, the costs of operating either shredder would be the same.
