Lena's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Lena S4.10 per pound, and type B coffee costs $5.95 per pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $336.00. How many pounds of type A coffee were used?

Just bought 21 pounds of coffee A

Step-by-step explanation:

We know that she consumed twice as many pounds of Type                              B coffee as type A.Then let the total number of cafe feet A=x ; then the                              number of cafe feet B=2x . We also know that the total number of feet cost $336And the fact that one pound of coffee A costs $ 4.1 ; and one pound of coffee B costs $ 5.95 Then :

The answer would be $68.04
