In a restaurant, a burger costs $9, and a pizza twice as much. How much would cost one pizza and three burgers? Let's think first. Chain of thought:
User
One pizza costs twice as much as the burger, which means 9 * 2 = $18. Three burgers would cost 9 * 3 = $27. So one pizza and three burgers would cost in total 18 + 27 = $45.
Therefore, the answer is 45.
