A farmer keeps some animals on a strict diet.  Each animal is to receive 15 grams of protein and 7.5 grams of carbohydrates.  The farmer uses two food mixes: Mix A = 12% protein and 9% carbohydrates; Mix B = 15% protein and 5% carbohydrates.  How many grams of each mix should be used to provide the correct nutrients for each animal?  The textbook is Intermediate Algebra 7th Ed. by Gustafson/Frisk.  ISBN 0-534-46342-8 and the question is on pg. 173 question 64. </SPAN>\n" );
