Answer 2

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 $x+y=430$ or $x=430-y$    .....(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:

$280x+125y=95600$      .....(2)

Substituting the value of x from (1)

$280(430-y)+125y=95600$

=> $120400-280y+125y=95600$

=> $-280y+125y=95600-120400$

=> $-155y=-24800$

y = 160

And x = $430-160$

x = 270

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