To determine

To calculate: The lowest-cost diet meeting specifications like one cup of uncooked rice costs 21 cents and contains 15 grams of protein, 810 calories and $\frac{1}{9}$ milligram of riboflavin. On the other hand, one cup of uncooked soybeans cost 14 cents and contains 22.5 grams of protein, 270 calories and $\frac{1}{3}$ milligram of riboflavin. Suppose that the minimum daily requirement are 90 grams of protein, 1620 calories and 1 milligram of riboflavin using simplex method. Also, calculate the new cost for 1700 calories and range of h for which sensitive analysis on the effect of a change of h calories be valid.
