Answer:
Selection from four different suppliers
Total cost function:
d. y =550550+4.444.44X
Explanation:
This is the least among all the other three cost functions when x is applied to the function. The other functions will have higher values of x than option d.
The finance manager is always interested in minimizing costs. Since, the quality of the raw materials are the same, it makes financial and economic sense for the finance manager to choose option d with the lowest total cost function.
We decided the choice based on the dependent values of the functions with constant intercept value of 550550.
The intercept (often labeled the constant) is the expected mean value of Y when all X=0.
