Question

The cost of renting a tool is $30 for the first three days, $10 per day for the next 5 days and $6 per day thereafter. If the input is the number of days the tool was rented, compute the cost of renting the tool. (C++)

Answer 1

#include <iostream>

using namespace std;

int main()
{
    int n, cost;
    
    cout<<"Enter number of days the tool was rented: ";
    cin>>n;
    
    if(n<=3){
        cost = n * 30;
    }
    else if(n<=8){
        cost = (3*30) + ((n-3)*10);
    }
    else{
        cost = (3*30) + (10*5) + ((n-8)*6);
    }
    
    cout<<"The cost of renting the tool: "<<cost<<endl;
    
    return 0;
}

Output:

Enter number of days the tool was rented: 7 The cost of renting the tool: 130
