I need help with this please

A t-shirt shop sells shirts that retail for $16. Quantity discounts are given as follow:
Number of Shirts Discount
10-20 10%
21-40 15%
41-60 20%
61 or more 25%

Write a C++ program that prompts the user for the number of shirts required and then computes corresponding discount, and the total price. Assume a sale tax of 11.5%. The program will display the customer saving (discount in dollars), sales tax in dollars and the total price

Hello cu123,

(Also, sales tax of 11.5%??? I'm glad I don't live wherever you are.)

There is a problem very similar in the Forum but I don't know how to add the sale tax. ** I don't know how to do the last two sentences

[Ganado]

Assuming that any sales tax is calculated after the discount, you'd just do something like this:

#include <iostream>

int main()
{
    double total_price_pre_tax = 42.00;
    double sales_tax = 0.115; // 11.5%

    double total_price = total_price_pre_tax + total_price_pre_tax * sales_tax;
    
    std::cout << "Price:       " << total_price_pre_tax << '\n';
    std::cout << "Sales tax:   " << sales_tax * 100.0 << "%\n";
    std::cout << "Total price: " << total_price << '\n';
}

If Douglas Adams were still alive you could ask him.
