Farmer Brown planted corn and wheat on his 1150 acres of land. The cost of planting and harvesting corn is $280 per acre. The cost of planting and harvesting wheat is $140 per acre. If Farmer Brown total cost was $249200, how many acres of corn did he plant?
Answer provided by our tutors
Let
x = the acres of corn planted
y = the acres of wheat planted
Farmer Brown planted corn and wheat on his 1150 acres of land:
x + y = 1150
Farmer Brown total cost was $249200:
280x + 140y = 249200
We have the following system of equations:
x + y = 1150
280x + 140y = 249200
