A coffee house blended 12 pounds of espresso flavored coffee beans with 11 pounds of vanilla flavored coffee beans. The 23 pound mixture cost $166.50. A second mixture included 17 pounds of espresso flavored coffee beans and 18 pounds of vanilla flavored coffee beans. The 35 pound mixture cost $254. Find the cost per pound of the espresso and vanilla flavored coffee beans.

Answer 1

espresso: $7.00 per pound

vanilla: $7.50 per pound

Explanation:

It is convenient to use the matrix functions of your graphing calculator to solve this system of equations:

• 12e +11v = 166.50
• 17e +18v = 254.00

The result is that ...

e = 7.00

v = 7.50

The cost per pound of espresso flavored beans is $7.00, of vanilla flavored beans is $7.50.
