How many pounds of coffee Worth $1.00 per pound must be mixed with
15 pounds of coffee worth $100 per
pound to obtain a blend worth $1.20
per pound?

the number of pounds that should be mixed is 30 pounds

Step-by-step explanation:

The computation of the number of pounds that must be mixed is shown below:

Let us assume the number of pounds be x

Now the equation is

(x) (1) + (15) (1.60) = (x + 15) (1.20)

x + 24 = 1.20x + 18

24 - 18 = 1.20x - x

6 = 0.20x

x = 30 pounds  

Hence, the number of pounds that should be mixed is 30 pounds
