A company is implementing a new pricing strategy using Salesforce CPQ to optimize its sales process. The sales team has identified three different pricing models: a flat rate, a tiered pricing model, and a volume-based discount model. If the company sells 100 units at a flat rate of $50 per unit, 150 units at a tiered rate where the first 100 units are $50 each and the next 50 units are $45 each, and 200 units at a volume-based discount where the price per unit decreases by $5 for every additional 100 units sold beyond the first 100 units (starting at $50), what will be the total revenue generated from these sales?
