7. Now assume Bridgeton is considering selling both high-end and low-end grinders. Assume the maximum total number of grinders produced sold (lower-end and higher-end combined) is 45,000, due to capacity constraints. Further, assume that, due to limited demand, Bridgeton estimates it can sell, at most, 30,000 high-end units and at most 45,000 low-end units. Should Bridgeton sell all high-end units, all low-end units, or a mix of high- and low-end units? Explain your reasoning
