solution

You are going to buy two items from a market for the day: banana and chocolate. Each banana costs 5 TL, and each bar of chocolate costs 9 TL. Each banana contains 4 grams of fiber and 2 grams of protein. Each bar of chocolate contains 1 gram of fiber and 1 gram of protein. Your doctor prescribed you to take at least 16 grams of fiber and 12 grams of protein daily. You love chocolates, so you want to eat at least 2 bars daily. Assume you consume no other food that contains fiber and protein for the day. You want to determine what to buy to minimize total cost.

a) Determine the sensitivity ranges for the cost of a banana and a bar of chocolate.
b) Usingthesensitivityrangesyoufoundinpart(b),determinethenewoptimalsolutionand

objective function value if the cost of banana is increased from 5 TL to 10 TL.
c) Determine the sensitivity ranges for the RHS of constraints (except nonnegativity constraints).
