A farmer grows only pumpkins and corn on her 420acre farm. This year she wants to plant 250 more acres of corn than pumpkins. How many acres of each crop should the farmer plant?

335 acres of corn
85 acres of pumpkins 
x+(x+250)=420
2x+250=420
x=85
85+250=335
Therefore,
335 acres of corn and 85 acres of pumpkins
