How many pounds of premium coffee at $12.50 Per pound have to be added with a cheap brand that costa $4.50 per. Pound in order to produce 72 pounds of a mixed blend that sells for $15.00 for a two pound bag?

We would need 12 pounds each to make a blend thag would cost $10 per pound.

I'm not completely sure. Let me know if this helps. :)

27 lbs premium coffee and 45 pounds cheap brand

Step-by-step explanation:

set up a system of equations

12.5P+4.5C = $15

p+c = 12

(solve this by elimination or substitution)

you get p = 3/4 and C = 5/4

This means it must be in a ration of 3 to 5.

3+5 = 8

and total 72 lbs/8 lbs = 9

3 x 9 = 27  and 5 x 9 = 45

ha!
