DFor the remaining questions, consider the following problem description:An oil company is considering exploring new well sites S1, S2, ..., S10 with respective costsC1, C2, C10 And in particular they want to find the least-cost selection of 5 out of the 10 possiblesites. The binary decision variables X1, X2, X10 denote the decision to explore the correspondingsite. Provide the best interpretation of the constraint: x1 + x7 + x8 ≤2Exploring site S₁ or S7 requires you to explore site SgExploring the site S₁ requires exploration of S7 or SgExploring sites S1, S7, and Sg is only possible if another constraint is disjunctiveExploring the combination of sites S₁ and S7 prevents you from exploring Ss

Another issue to research when purchasing ahome is that of points and mortgage interestrates. Usually paying higher points results in alower mortgage interest rate. The question forthe homebuyer is: Should I pay higher points fora lower mortgage interest rate, or pay lowerpoints for a higher mortgage interest rate? Theanswer to that question depends on manyfactors, one of which is the amount of time thehomeowner plans on staying in the home.Consider two typical situations for a 30-year,$100,000 mortgage. Option 1 offers an annualmortgage interest rate of 8.25% and a loanorigination fee of 3.5 points. Option 2 offers anannual interest rate of 8% and a loan originationfee of 4points. What is the total amount paid, including points, after 3 years for each option? ( Round your answers to the nearesr cent.) Option 1:Option 2:

At Long John Silver’s (LJS), Platter 1 comes with 2 pieces of fish, 3 pieces of chicken, and 5 fried shrimp, while Platter 2 comes with 3 pieces of fish, 1 piece of chicken, and 8 fried shrimp. Platter 1 sells for 8 dollars and platter 2 sells for 10 dollars. If LJS has access to 1000 pieces of fish, 1200 pieces of chicken, and 2600 fried shrimp, what is the optimal number of platters LJS should make in order to maximize its profit? Note that the constraints relate to (please use these in order) fish, chicken, and shrimp. Note that problem 7 had three constraints (excluding the non-negativity constraints), and setting two pairs of those constraints to equality led to two extreme points on the feasible region. What INFEASIBLE point was at the intersection of the other pair of constraints? In the optimal solution to problem 7, the optimum was found at the intersection of two of the constraints that were not non-negativity constraints. Call these “binding” constraints. One of those…
