A chemical plant CleanCo designs a new plant to produce four different cleaners for kitchen, bath, glass and floor. The minimum demand for each of these cleaning solutions is 1000, 3200, 2800 and 5400 litres, respectively. Two suppliers Chemic and Nevich, are supplying needed chemicals to the CleanCo for production. Due to safety reasons, CleanCo cannot buy more than %75 of the chemicals from the same supplier. Two suppliers’ chemicals have different rates to produce cleaning products. 1 litre of Chemic can produce 0,75 ltr of kitchen, 0,65 ltr of bath, 0,85 ltr of glass, and 0,72 ltr of floor cleaner. The corresponding rates from Nevich are 0,82 0,78 0,55 and 0,75 respectively. CleanCo needs to determine the minimum capacity of the new plant. Model the problem
