Final answer:
The break-even quantity, beyond which the second process becomes more attractive than the first, is approximately 590 units.
Step-by-step explanation:
To determine the break-even quantity, we need to find the point at which the total costs of the two manufacturing processes are equal. Let's represent the break-even quantity as x. For the first process, the total cost equation is TC = 49700 + 740x. For the second process, the total cost equation is TC = 391000 + 160x. To find the break-even quantity, we set these two equations equal to each other and solve for x:
49700 + 740x = 391000 + 160x
Simplifying the equation:
580x = 341300
x ≈ 589.48
Therefore, the break-even quantity, beyond which the second process becomes more attractive than the first, is approximately 590 units.
