the modern grocery has a cashews that sell for $5.00 a pound and peanut that sell for $2.75 a pound. How much of each must Albert, the grocer, mix to get 90 pounds of a mixture that he can sell for $3.00 per pound?
let cashews = x pound
peanut = 90-x pound
total cost = 5x + 2.75(90-x)
=> 90*3 = 2.25x + 247.5
=> 22.5 = 2.25x
=> x =10
cashew = 10 pound
peanut = 80 pound
