To make a flour mixture, a miller combined soybeans that cost $8.50 per bushel with wheat that cost $4.50 per bushel. How many bushels of each were used to make a mixture of 800 bushels costing $5.50 per bushel?
Let x = number of bushels of soybeans
Let y = number of bushels of wheat
x + y = 800
8.50x + 4.50y = (800)(5.50) = 4400
from the first equation
y = 800-x
8.50x + 4.50(800-x) = 4400
8.50x + 2000 - 4.50x = 4400
4x = 2400
x = 600
y = 800-600 = 200
