Answer:

The farmer planted 270 acres of corn and 160 acres of wheat.

Step-by-step explanation:

Let the acres of corn be = x

Let the acres of wheat be = y

Total acres of land = 430

So, we have [tex]x+y=430[/tex] or [tex]x=430-y[/tex]    .....(1)

The cost of planting and harvesting corn is $280 per acre. The cost of planting and harvesting wheat is $125 per acre. The farmer spent $95600 on plantation.

We get another equation as:

[tex]280x+125y=95600[/tex]      .....(2)

Substituting the value of x from (1)

[tex]280(430-y)+125y=95600[/tex]

=> [tex]120400-280y+125y=95600[/tex]

=> [tex]-280y+125y=95600-120400[/tex]

=> [tex]-155y=-24800[/tex]

y = 160

And x = [tex]430-160[/tex]

x = 270

So, the farmer planted 270 acres of corn and 160 acres of wheat.
