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.
