Answer:
11 2/3 pounds.
Step-by-step explanation:
Let x pounds be the amount in pounds of Brazilian coffee.
x + 27 is the amount of coffee in lbs after the mixing.
So ,working in values of dollars, we have:
6x + 4*27 = 4.5(x + 27)
6x + 104 = 4.5x + 121.5
1.5x = 121.5 - 104 = 17.5
x = 17.5/1.5 = 11 2/3 pounds answer
