Final answer:
The switch-over point from buying the product to making it on the standard machine occurs when the company needs more than 890 units.
Step-by-step explanation:
The student is asking to calculate the switch-over point or the point of intersection between the buy option and make-option 1 in a company's manufacturing operations. To find the switch-over point, we must compare the total cost of buying versus making the product on a standard machine. The cost of buying is a constant $230 per unit. The total cost of making the product includes both the variable cost of $170 per unit and the fixed cost of the standard machine, which is $53,400. The switch-over point occurs where the total costs of both options are equal. Therefore, we need to solve for the number of units (Q) where:
230Q = 170Q + 53,400
By rearranging the equation and solving for Q, we get:
60Q = 53,400
Q = 890
Thus, the company should switch from buying the product to making it on the standard machine when it requires more than 890 units.
