怎么理解money=13+(distence-3)*2.3*0.2，这样不是算少了吗

Question

#include <stdio.h>double Money(double time, double distence){ double money = 0; if (time<0 || time >= 24) { printf("错误"); return 0; } else if (distence <= 3) { money = 13; } else if (time >= 5 || time<23) { money = 13 + 2.3*(distence - 3); } else money = 13 + 2.3*(distence - 3)*0.2; return money + 1;}int main(){ printf("小明打的总费用为%f元", Money(9, 12) + Money(18, 12)); return 0;}
