📋 The situation
Maria wants to start a food truck. She has two ways to get one:
🚚 Option A — Rent
A one-time setup fee of $2,000, plus $150 per week of rental.
💰 Option B — Buy
Buy a used truck outright for $5,000, with $50 per week in maintenance.
Let w = the number of weeks. Total cost is modeled by a linear equation for each option.
