Consider the problem of calculating the median m of the following numbers: 4,5,9. (a) Write down the linear program that you could solve, to find the median m. Then put this LP in the form: min c^T x s.t. Ax 2 b, x 2 0, where x is your list of variables. (b) Now write down the dual of the problem above. Call the list of dual variables y. (Hint: there are 6 components of y.)

A certain university is considering the purchase of N95 masks to distribute to their students for protection against the next variant of the covid virus. They found a reliable distributor who offers N95 masks with a quantity discount. The pricing is shown below. Number of N95 masks Price per mask From To 500 $1.23 501 2000 $0.98 2001 5000 $0.62 5001 or more $0.53 For example, if the university purchases 700 masks the price is 500 × $1.23 = $615.00 for the first 500 masks plus (700 – 500) × $0.98 = $196.00 for the next 200 masks for a total of $615.00 + $196.00 = $811.00. Write a MATLAB program that first prompts the user to input the number of masks. Use the following prompt: Please enter the number of N95 masks: Then, based on the number entered and the above table, calculate the purchase price. Output to the command window the number of masks and the purchase price as follows: Your price for xXXx N95 masks is $xxx.xx where xxxx is the number of masks and $xxx.xx is the price. If the…
