Buford should use 7.5 pounds of the 50% corn bag.

How do we solve a system of linear equations from word problems?

A system of linear equation is an equation containing two different equations with variables and the coefficient.

From the given information, let:

  • The weight of the bag containing 50% corn be = x
  • The weight of the bag containing 90% corn be = y

Sp, we can a system of a linear equation that says:

x + y = 30

0.5x + 0.9y = 0.8(30)

Using elimination method

x + y = 30

-

x - 1.8y = -48

0 - 0.8y = -18

y = 18/0.8

y = 22.5

From x + y = 30

x = 30 - 22.5

x = 7.5

Therefore, we can conclude that he should use 7.5 pounds of the 50% corn bag.
