The amount of
coffee is 
.
Further explanation:
Given information:
A merchant has a pound of coffee of worth
.
That merchant wants to mix
of coffee that worth 
a pound with the coffee that’s worth is 
.
After that the merchant wants to sell that mixture for
a pound.
Calculation:
Let us consider the amount of
coffee be 
pounds.
The merchant wants to mix that
pound of 
coffee with 
of 
coffee.
Therefore, the total mixture would be of
pounds.
Now, the total worth of the mixture of
coffee and 
coffee is calculated as follows:
The merchant wants to sell the total mixture for
a pound.
Therefore, the merchant’s earning would be
dollars.
The worth of the mixture would be equal to the total earnings.
Therefore, the amount
of 
coffee can be calculated as follows:
Use distributive property to expand the Left-Hand Side of above equation as follows:
Simplify the above equation to find the value of
as shown below:
Divide both sides by
in above equation as follows:
Therefore, the value of
is 
.
Thus, the amount of
coffee is 
.
