Belton is hosting a festival where vendors can pay to have a small booth or a large booth. The fee for a small booth is $85, and the fee for a large booth is $200. The city hopes to receive at least $3,700 in fees. Which inequality models this situation? Let x equal the number of small booths and y the number of large.

• 3700 - 200y = 85x
• 200y - 85x > 3700
• 85x + 200y ≥ 3700
• 85x + 200y ≤  3700
