Step-by-step explanation:
To find the price for 1 pound of the mix, we can calculate the weighted average of the prices of Brazilian and Ethiopian coffee based on their proportions in the mix.
Let's denote the price per pound for Brazilian coffee as
�
B and for Ethiopian coffee as
�
E.
In this case:
B = $6 (price of Brazilian coffee per pound)
E = $8 (price of Ethiopian coffee per pound)
The mix consists of 5 pounds of Brazilian coffee and 3 pounds of Ethiopian coffee.
The total weight of the mix is
5
+
3
=
8
5+3=8 pounds.
Now, calculate the weighted average price (

total weight of the mix
WAP=
total weight of the mix
(B×weight of Brazilian coffee)+(E×weight of Ethiopian coffee)

WAP=

(6×5)+(8×3)

WAP=

30+24

6.75
WAP=6.75
Therefore, the price for 1 pound of the mix is $6.75.
