javascript - jquery价格表斐波那契

Question

嗨，我有一个 javascript 函数应该可以定价，但我没有找到任何可以帮助我的 jquery 函数。这是背后的逻辑

1 user to 4 will pay = 40 / user so 3users = 120
5 users to 9 will pay = 36/ user so 7 users = 268
10 users to 19 will pay = 32/user so 15 users =  564 
20 users to 49 will pay 28/user so 40 users = 1220
50 users to 99 will pay 24/ user so 60users  = 1860
100 users to infinite will pay 20/ user so 114 users = 3000

我需要某种函数来做到这一点，我试图用多个数组和函数来检查它是否在两个数字之间......

我想我明白了，所以这样的事情可能会奏效：

function getTotal(num_users) {
    var amount = 0;
    if (num_users >= 100) {
        amount = 20;
    } else if (num_users  >= 50) {
        amount = 24;
    } else if (num_users  >= 20) {
        amount = 28;
    } else if (num_users  >= 10) {
        amount = 32;
    } else if (num_users  >= 5) {
        amount = 36;
    } else if (num_users  >= 1) {
        amount = 40;
    }
    return num_users*amount;
}
