The area covered by corn is x The area covered by wheat is (x+480) After 80% of wheat was collected, the new area was: 20/10(x+480) =1/5(x+480) After 25% of the corn was collected, the new area was: 75/100x =3/4x New area equation will be: (3/4)x=1/5(x+480)+300 (3/4x)=(1/5)x+96+300 solving for x we get: 11/20x=396 x=720 thus the original area of corn was 720 acres Original area of wheat was 720+480=1200 acres
<em>Isolate the variable by subtracting 7 from all 3 parts of the inequality, and then dividing each part by 2. To solve inequalities like a < x < b, use the addition and multiplication properties of inequality to solve the inequality for x.</em>
