Ingredient A provides 16 units of protein and 4 units of vitamins per pound. Ingredient B provides 8 units of protein and 8 units of vitamins per pound. Ingredients A and B cost $0.50 and $0.20 per pound, respectively. The company wants its dog food to contain at least 12 units of protein and 6 units of vitamins per pound and be as inexpensive as possible.\r

If you do a T chart you'll see that the ratios are the same in A and B. In brief:
\n" ); document.write( "### p v
\n" ); document.write( "A: 16 4
\n" ); document.write( "B:_ 8 8
\n" ); document.write( "-------------------- p v
\n" ); document.write( "A: 1/2(16), 1/2(4) = 8 2
\n" ); document.write( "B: 1/2(8) , 1/2(8) = 4 4
\n" ); document.write( "Mix . . . . . . . .= 12 6 Correct \n" ); document.write( "
