Final answer:
The farmer should plant 85 acres of pumpkins and 335 acres of corn on her 420-acre farm to have 250 more acres of corn than pumpkins.
Step-by-step explanation:
The task is to determine how many acres of pumpkins and corn the farmer should plant on her 420-acre farm given that she wants to plant 250 more acres of corn than pumpkins. To solve this, we set up a system of equations:
- Let x represent the number of acres of pumpkins.
- Let x + 250 represent the number of acres of corn.
The sum of the acres for both crops is the total farm size: x (pumpkins) + (x + 250) (corn) = 420 acres.
Solving the equation:
- x + (x + 250) = 420
- 2x + 250 = 420
- 2x = 420 - 250
- 2x = 170
- x = 85
So, the farmer should plant 85 acres of pumpkins and 335 acres of corn (85 + 250).
