急！！C program stpm ict

ThomasWoh

大家好，我是stpm ict学生
这次我遇到难题了，就是要写 如图 的 c program
how many kids 开始
我就不懂怎么写了，因为我写到很长，老师不要，因为她说很乱
第一个孩子没有discount，两个开始就有discount total price 10%，请问各位会写 c 的大大，可以给点tips?

我 B1 的 code 是

#include <stdio.h>                                                                                                       

int main()
{
        printf("Welcome to Sayang Pintar Kindergarten and Nursery\n");
        printf("-------------------------------------------------\n\n");
        printf("Packages offered are as follows:\n\n");
        printf("Package 1: Kindergarten(8.30 a.m. - 12.30 p.m.)\nMonthly fee for package 1: RM170.00\n\n");
        printf("Package 2: Kindergarten and Nursery(7.00 a.m. - 3.00 p.m.)\nMonthly fee for package 1: RM320.00\n\n");
        printf("Package 3: Kindergarten and extended Nursery(7.00 a.m. - 6.00 p.m.)\nMonthly fee for package 1: RM440.00\n\n");

        int choice;                                                                                                                                
        printf("Please choose your package: 1, 2 or 3: ");
        scanf("%d", &choice);                                                                                                        

        switch (choice)
        {
                case 1:                                                     
                printf("\n** Your monthly fee : RM170.00 **\n\n");
                break;
                case 2:                                                    
                printf("\n** Your monthly fee : RM320.00 **\n\n");
                break;
                case 3:                                                    
                printf("\n** Your monthly fee : RM440.00 **\n\n");
                break;
                default:                                             
                printf("\n** Invalid package **\n\n");
        }

        printf("Thank you!!\n");

        return 0;
}

printf("\n** Your total monthly fee: RM%.2f **\n\n",total);
printf("Thank you.");
