Answer: Hey!! Dear student kindly finds your solution below. Let me know if any issue. Thanks.

This C++ program takes necessary inputs, all calculations are done in this and print desired output as you mentioned in the problem.

#include<iostream>
using namespace std;
int main()
{

double REGULAR = 2.89,PLUS = 3.09,SUPER = 3.39;
char gas_type,car_wash;
double price,no_gallons,carwash_cost,total_price,type_price;
cout<<"Enter number of gallons and press<Enter>";
cin>>no_gallons;
cout<<"\nEnter gas type(R,P,S, or N) and press<enter>";
cin>>gas_type;
cout<<"\nEnter Y or N for car wash and press<enter>";
cin>>car_wash;
if(gas_type == 'R')
{
type_price = REGULAR;
price = no_gallons*REGULAR;
}
else
if(gas_type == 'P')
{
type_price = PLUS;
price = no_gallons*PLUS;
}
else
if(gas_type == 'S')
{
type_price = SUPER;
price = no_gallons*SUPER;
}
else
{
price = 0;
}
if(car_wash == 'Y')
{
if(price>10)
{
carwash_cost = 1.25;
}
else
{
carwash_cost = 3.00;
}
}
else
if(car_wash == 'N')
{
carwash_cost = 0;
}
total_price = price+carwash_cost;
cout<<"\n******************************************"<<endl;
cout<<"* *"<<endl;

cout<<"*******************************************";
cout<<"\nAmount Gasoline purchases   "<<no_gallons<<"Gallons";
cout<<"\nPrice per gallons $ "<<type_price;
cout<<"\nTotal gasoline cost $ "<<price;
cout<<"\nCar wash cost $ "<<carwash_cost;
cout<<"\nTotal due $ "<<total_price;

cout<<"\n\nThank you for stopping";
cout<<"\nPlease come again";
cout<<"\nRemember to buckle up and drive safety";
return 0;
}
