Question 1203944
.
Aldo's Coffee Shop makes a blend that is a mixture of two types of coffee. 
Type A coffee costs $4.10 Aldo per pound, and type B coffee costs per $5.15 pound. 
This month's blend used twice as many pounds of type B coffee as type A, 
for a total cost of 288.00. How many pounds of type A coffee were used?
~~~~~~~~~~~~~~~~~~


<pre>
x  = pounds of coffee type A;

2x = pounds of coffee type B.


The total cost equation

    4.10x + 5.15*(2x) = 288.00  dollars.


Simplify and find x

    4.10x + 10.30x = 288

        14.40x     = 288

             x     = 288/14.40 = 20.

<U>ANSWER</U>.  20 pounds of coffee type A.

Solved.
