Answer to Question #20189 in C++ for achmed

Question

in order to discourage excess consumption, an electric company charges its customers a lower rate, namely $0.11, for each of the first 250 kilowatt hours and a higher rate of $0.17 for each additional kilowatt hour. in addition, a 10% surtax is added to the final bill. write a program to calculate electric bills given the number of kilowatt hours consumed to input.use two function declarations: one to compute the amount due without the surtax and one to compute the total due. the declaration of the second function should include a call to the first function.

Answer 1

#include <iostream>
using namespace std;


float f1(float a){
float s;
if (a<250)
s=a*0.11;
else
s=250*0.11+(a-250)*0.17;
return s;
& }


float f2(float a){
& return f1(a)*1.1;
& }

int main(void)
{
float a;
cout<<"enter the number of kilowatt hours consumed : ";
cin>>a;
cout<<"total amount: "<<f2(a)<<endl;
system ("PAUSE");

}
