soybean meal is 16% protein; cornmeal is 8% protein. how many pounds of each should be mixed together in order to get 320-lb mix

nlexa [21]

Answer:

120 lb of soybean meal

200 lb of cornmeal

Step-by-step explanation:

S = pounds of soybean meal

C = pounds of cornmeal

S + C = 320 → C = 320 – S

0.16S + 0.08C = 0.11 × 320 = 35.2

16S + 8C = 3520

16S + 8(320 – S) = 3520

16S + 2560 – 8S = 3520

8S + 2560 = 3520

8S = 960

S = 120

C = 320 – 120 = 200

Three workers sort 66 boxes in a day one of the workers is three times more productive than the second worker and twice as produ

Mekhanik [1.2K]

<span>Let’s assign variables for each workers
Let x = number of boxes sorted by worker 1
Let y = number of boxes sorted by worker 2
Let Z = number of boxes sorted by worker 1

=> X = 3Y
=> X = 2Z
The equation would be:
=> X + Y + Z = 66
=> X + X/3 + X/2 = 66
=> 6X + 2 X + 3 X = 396
=> 11 X = 396
=> 11X / 11 = 396 / 11
=> X = 36

X = 36
Y = 36 / 3 = 12
Z = 36 / 2 = 18
=> 36 + 12 + 18 = 66
