Refer to "Problem C" in the packet for the following question.To be able to solve this problem on Solver or any computer program, the equations need to be transformed to have individual columns of the xj.This format is readily seen on the homework problems and handouts given in class.

The packet contains the LP as originally written.The model is correctly specified, but the constraints will need to be rewritten to be compatible with solving using either Solver or another LP computer package.

(1) Problem C, Question 1 of 1.Which of the following set or sets of constraints have all constraints correctly written?(10 points).
