A farm had 480 acres more wheat than corn. Let use "W" to represent the Wheat and let use "C" to represent the corn. Hence, we have below:
W=C+480

The farmers collected 80% of the wheat and 25% of the corn and the area of the wheat is 300 acres less than the area of the corn:
W-0.8W=C-0.25C+300
0.2W=0.75C+300
We have two equations, two unknowns:
0.2(C+480)=0.75C+300
0.2C+96=0.75C+300
0.55C=294
C=534.55

Answer:

wheat acres is 1200.Corn acres is 720.

Step-by-step explanation:

A farm had 480 acres more wheat than corn.W represent wheat.C represents corn.So the equation for this part is:W=C+480.

After the farmers collected 80% of the wheat and 25% of the corn, the area of the wheat was 300 acres less than the area of the corn. So the equation is:W-w-0.8W+300=C-0.25C.which simplfies to:

0.2W+300=0.75C

we have 2 eqations with unknown variables.

W=C+480

0.2W+300=0.75C

we will use the substitution method by plugging in the first equation into the second equation.

0.2(C+480)+300=0.75C.

now solve for C.

0.2C+96+300=0.75C.

396=0.55C

C=720.

solve for W:

W=C+480
