Amerchant has coffee worth $20.00 per pound that she wishes to mix with 70 pounds of coffee with $90.00 per pound to get a mixture that she will sell for $30.00 per pound. how many pounds (lbs) of the $20.00 coffee should be used?

20x-1000 +4000 = 60x

20x-60x= -4000 +1000

-40x= -3000

x= -3000/-40

75 The mix will be 75 lbs

And $20 coffee will be 75 -50 = 25lbs
