`//Question #42085, Programming, C++`

#include <iostream>

using namespace std;

int main () {

const float salesTaxRate = 7;

const float interestRate = 9;

float price;

float downPayment;

int numberOfYears;

float monthlyPayment = 0;

cout << "Please enter the price of the car :\n";

cin >> price;

cout << "Please enter down payment :\n";

cin >> downPayment;

cout << "Please enter the number of years for the loan :\n";

cin >> numberOfYears;

price += price*(salesTaxRate / 100); //add to the price the tax for the sale

price -= downPayment;// price without downPayment

price += price*(interestRate/100); // add to the price interest Rate

monthlyPayment = price / (numberOfYears*12);

cout << "You will pay " << monthlyPayment << " in a month.\n";

return 0;

}
