Farmer planted corn and wheat on 1270 acres of land. The cost of harvesting and planting corn is $270 per acre. Cost of harvesting and planting wheat is $135 per acre. If Farmer's total cost was $264,600, how many acres of corn did he plant?
Answer provided by our tutors
c = acres of corn
w = acres of wheat
c+w=1270
270c+135w = 264600
w=1270-c
270c + 135(1270-c) = 264600
270c +171450-135c = 264600
135c=93150
c=690
w=1270-690=580
c= 690 acres of corn
w = 580 acres of wheat
