题目描述
PizzaForces is Petya's favorite pizzeria. PizzaForces makes and sells pizzas of three sizes: small pizzas consist of 6 slices, medium ones consist of 8 slices, and large pizzas consist of 10 slices each. Baking them takes 15, 20 and 25 minutes, respectively.
Petya's birthday is today, and n of his friends will come, so he decided to make an order from his favorite pizzeria. Petya wants to order so much pizza that each of his friends gets at least one slice of pizza. The cooking time of the order is the total baking time of all the pizzas in the order.
Your task is to determine the minimum number of minutes that is needed to make pizzas containing at least n slices in total. For example:
- if 12 friends come to Petya's birthday, he has to order pizzas containing at least 12 slices in total. He can order two small pizzas, containing exactly 12 slices, and the time to bake them is 30 minutes;
- if 15 friends come to Petya's birthday, he has to order pizzas containing at least 15 slices in total. He can order a small pizza and a large pizza, containing 16 slices, and the time to bake them is 40 minutes;
- if 300 friends come to Petya's birthday, he has to order pizzas containing at least 300 slices in total. He can order 15 small pizzas, 10 medium pizzas and 13 large pizzas, in total they contain 15⋅6+10⋅8+13⋅10=300 slices, and the total time to bake them is 15⋅15+10⋅20+13⋅25=750 minutes;
- if only one friend comes to Petya's birthday, he can order a small pizza, and the time to bake it is 15 minutes.
PizzaForces 是 Petya 最爱的披萨店。PizzaForces 制作并销售三种尺寸的披萨:小号披萨包含 6 片,中号披萨包含 8 片,大号披萨包含 10 片。它们的烘焙时间分别为 15、20 和 25 分钟。
今天是 Petya 的生日,将有 n 位朋友前来参加,因此他决定从这家最爱的披萨店下单。Petya 希望订购足够多的披萨,使得每位朋友至少能分到一片披萨。订单的烹饪时间等于订单中所有披萨的烘焙时间之和。
你的任务是确定制作总共至少包含 n 片披萨所需的最少分钟数。例如:
- 若有 12 位朋友来参加 Petya 的生日聚会,则他需订购总共至少 12 片披萨。他可以订购两个小号披萨,恰好共 12 片,烘焙时间为 30 分钟;
- 若有 15 位朋友来参加 Petya 的生日聚会,则他需订购总共至少 15 片披萨。他可以订购一个小号披萨和一个大号披萨,共 16 片,烘焙时间为 40 分钟;
- 若有 300 位朋友来参加 Petya 的生日聚会,则他需订购总共至少 300 片披萨。他可以订购 15 个小号披萨、10 个中号披萨和 13 个大号披萨,总计 15⋅6+10⋅8+13⋅10=300 片,总烘焙时间为 15⋅15+10⋅20+13⋅25=750 分钟;
- 若仅有 1 位朋友来参加 Petya 的生日聚会,则他可订购一个小号披萨,烘焙时间为 15 分钟。
