Question

Create a function called ApplyTax. The tax rate should be a const set to 8.75%. ApplyTax should take in a number and return it with the tax. Create a function called TotalCost. It should take in the amount of an item (for instance, 13 items are purchased), the name of the item, and the cost of the item. If 100 to 200 items are purchased, there is a 10% discount, if 200 to 300 items are purchased there is a 15% discount, if more than 300 items are purchased there should be a 20% discount. The TotalCost function should use ApplyTax to find the total cost. It should output to the console the item name, amount purchased, and total cost of the item. You should run the function TotalCost 3 times (from main), using a loop, each time having the user fill in the relevant info for a new product.

Answer 1

Certainly, here's a C++ program that includes the functions ApplyTax and TotalCost, and uses a loop to run TotalCost three times with user input:

```cpp
#include
#include

const double TAX_RATE = 0.0875; // 8.75% tax rate

double ApplyTax(double amount) {
return amount * (1.0 + TAX_RATE);
}

double TotalCost(int amount, const std::string& item, double cost) {
double total = cost * amount;
if (amount >= 100 && amount < 200) {
total *= 0.9; // 10% discount
} else if (amount >= 200 && amount < 300) {
total *= 0.85; // 15% discount
} else if (amount >= 300) {
total *= 0.8; // 20% discount
}
return ApplyTax(total);
}

int main() {
for (int i = 1; i <= 3; ++i) {
std::string item;
int amount;
double cost;

std::cout << "Enter the item name: ";
std::cin >> item;
std::cout << "Enter the amount purchased for " << item << ": ";
std::cin >> amount;
std::cout << "Enter the cost of one " << item << ": $";
std::cin >> cost;

double total = TotalCost(amount, item, cost);
std::cout << "Item: " << item << ", Amount: " << amount << ", Total Cost: $" << total << std::endl;
}

return 0;
}
```

This program defines the ApplyTax and TotalCost functions as described and uses a loop to run TotalCost three times, each time taking user input for a different product. It calculates the total cost, applying discounts as specified, and then applies the tax using ApplyTax.
