A pizzeria offers two types of deals: individual pizzas and soda six-packs. The graph above shows the combinations of individual pizzas (x-axis) and soda six-packs (y-axis) that can be purchased for a total of $50.00. The point (5, 0) and (0, 25) are on the graph. If a customer's budget increases to $75.00, and the prices of individual pizzas and soda six-packs remain the same, what will be the new x-intercept of the graph?
