You are a farmer and want to spend under $35,000 on farm equipment. You need a hay baler that costs $6,250 and several plowing disks cost $2,500 each. Write an inequality that models how many plowing disks could be purchased within your budget. What is the maximum number of plowing disks you can buy?

A 2,500x + 6,250 < 35,000; 11 plowing disks2,500x + 6,250 < 35,000; 11 plowing disks
B 2,500x + 6,250 ≤ 35,000; 11 plowing disks2,500x + 6,250 ≤ 35,000; 11 plowing disks
C 2,500x + 6,250 < 35,000; 12 plowing disks2,500x + 6,250 < 35,000; 12 plowing disks
D 2,500x + 6,250 ≤ 35,000; 12 plowing disks
