Oakton Manufacturing makes two types of rocking chairs known as the Big and Small models. Each chair requires four legs and two rockers but differing numbers of wooden dowels. Each Big chair requires four short dowels and eight long dowels while each Small chair requires eight short dowels and four long dowels. Each Big chair contributes $10 in profit while each Small chair contributes $12. The company has 900 legs, 400 rockers, 1,200 short dowels, and 1,056 long dowels available. The company wants to maximize its profit while also ensuring that it makes at least half as many Big chairs as Small chairs. a. Formulate an LP model for this problem.
