Explanation Given: A butcher makes a blend of stew meat from beef that sells for $2.80 a pound and pork that sells for $3.25 a pound. Calculation: A butcher makes a blend of stew meat from beef that sells for $2.80 a pound and pork that sells for $3.25 a pound. Let x be the number of pounds of stew of beef and y be the number of pounds of stew meat of pork. The blend of both the stew meats of 30 pounds: x + y = 30 …...…... (1) Since, the blend of two stew meats can be sold for $3.10 a pound. Then, the cost of 30 pounds of blend of both the stew meat is 30(3.10) =$93 The cost of stew meat of beef is $2.80 a pound and the cost of stew of pork is $3.25 a pound. Therefore, 2.80 x + 3.25 y = 93 …...…... (2) Solving the equation (1) and (2). From equation (1), y = 30 − x . Put in equation (2) to get: 2.80 x + 3.25 y = 93 2.80 x + 3.25 ( 30 − x ) = 93 2
