FireBurst Electronics produces memory units for specialized applications. Unit A provides 2 GB of high-bandwidth memory and 15 GB of low-bandwidth memory. Unit B provides 0.5 GB of high-bandwidth memory and 60 GB of low-bandwidth memory. Unit A costs $12.50 and Unit B costs $7.50. A particular application requires at least 35 GB of high-bandwidth memory, and 648 GB of low-bandwidth memory, and cannot use more than 28 individual units. How many of each memory unit should FireBurst Electronics use to meet this requirement and minimize the cost of the product? Formulate a linear programming model for this situation. Solve this model using graphical analysis. Display your graph and the solution parameters.
