You work at a restaurant that sells sandwiches. Your manager, who is not a good manager, underestimated the business for the weekend, and you have now run out of certain meats for the sandwiches. He sends you to the grocery store across the street to buy some meat. You end up buying 8 pounds of turkey for $11.50, and 5 pounds of roast beef for $13.25. Assuming that the relationship between pounds and price is linear, find the line of best fit equation to model the situation.
