Question 779579: whats is the answer for this formula ?
A coffee merchant combines coffee that costs $6 per pound with coffee that costs $4.20 per pound. How many pounds of each should be used to make 22 lb of a blend costing $5.55 per pound?
$6 per lb coffee lb
$4.20 per lb coffee lb
You can put this solution on YOUR website! Price ---------------- quantity
Coffee Type I $6.00 ---------------- x pounds
Coffe type II $4.20 ------ 22 - x pounds
Mixture $5.55 ---------------- 22
22
6 x + 4.2 ( 22 - x ) = 122.1
6 x + 92.4 - 4.2 x = 122.1
6 x - 4.2 x = 122.1 - -92.4
1.8 x = 29.7
/ 1.8
x = 16.5 pounds $6.00 Coffee Type I
5.5 pounds $4.20 Coffee type II
