Please help with those questions

1.       In the Orange blending problem, the boss says that he has a budget of $1,500,000. The procurement should be done to consume as much of the budget as possible, while maintaining the constraints already set, but removing the constraint on the maximum quantity to be purchased. There is no upper limit for purchases, in each month.

 What changes should be made to the original model, to accomplish this goal. Is there a viable solution? If so, what is the purchase cost determined by the model?

2.       In the Orange blending problem, the procurements should be done in full units of thousands of gallons. Fractional amount of thousands of gallons is not allowed. Apply the necessary constraints, and determine what is the purchase cost determined by the model?

Hint: Solver Options, uncheck “Ignore integer Constraints” also
