Fred's coffee shop makes a blend that is a mixture of two types of coffee. Type A costs Fred $5.50 per pound and type B coffee cost $4.30 per pound. This month, Fred made 133 pounds of the blend, for a total of $667.90. How many pounds of type A did Fred use?
\n" ); document.write( "
Let amount of Type A be A\r\n" );
document.write( "Then amonunt of Type B is 133 - A\r\n" );
document.write( "We then get the following BLEND-cost equation: 5.5A + 4.3(133 - A) = 667.9\r\n" );
document.write( "5.5A + 4.3(133) - 4.3A = 667.9\r\n" );
document.write( "5.5A - 4.3A = 667.9 - 4.3(133)\r\n" );
document.write( "1.2A = 96\r\n" );
document.write( "Amount of Type A, or \"highlight_green%28matrix%281%2C6%2C+A%2C+%22=%22%2C+96%2F1.2%2C+%22=%22%2C+80%2C+lbs%29%29\"\r\n" );
document.write( "\r\n" );
document.write( "Should be pretty easy for you to now determine how much of Type B was used in the blend. \r\n" );
document.write( "\r\n" );
document.write( "BTW...the other person's response will NEVER get you the correct answers. As a matter of fact, a RIDICULOUSLY\r\n" );
document.write( "high amount for A would be derived.....an amount that's over 30 times as great as the total. As a result, a \r\n" );
document.write( "RIDICULOUSLY high NEGATIVE amount for Type B would ensue. Can this be? I leave you to ponder this!
