The Olde English Tea Company makes two brands of tea

The Olde English Tea Company makes two brands of tea, each of which is a blend of tea leaves from several sources. Sophisticated tea drinkers with sensitive noses respond more strongly than other consumers to a tea’s fragrance and taste, so that the firm’s premium brand commands a higher price than its standard brand. The table below lists information on the fragrance and taste ratings of tea leaves from the different sources, as well as the minimum quality standards for the firm’s two brands.

Tea leaves from Source A                               90                                            85

Tea leaves from Source B                               85                                            90

Tea leaves from Source C                               80                                            75

Standard brand of Tea                                     77                                            81

Further, the costs and availability of the different sources of tea leaves is as follows:
