Question

I am almost done with this code but am having a problem when the code is calculating an kw usage. When I enter:

Southwest Power and Light

Billing Statement

Please enter your name > b,b

Customer name:b,b

Meter reading date > 2/15/16

Meter reading date:2/15/16

Electricity used is > 550

Baseline charge $6.25

Over-baseline charge$6.25

Excess charge$6.25

The total amount due is 6.25Calculate another bill? (Y/N)?:

I'm not getting the right calculations even though the calculation code is correct. The output should show:

Electricity used is > 550

Baseline charge $35.00

Over-baseline charge $16.50

Excess charge $6.25

The total amount due is $57.75

Calculate another bill? (Y/N)?:

Explanation / Answer

The rest of the code is correct, please change the following in the calculations:

// calculations

if (kwUsed >= 0 && kwUsed <= 350)

{

baselineCharge = kwUsed*basicRate;

//System.out.print("The Baseline is ");

//System.out.printf("%.2f ",basicRate);

}

else if (kwUsed >= 351 && kwUsed <= 500)

{

baselineCharge=350*basicRate;
overbaselineCharge = overBaselineRate * (kwUsed-350);

//System.out.print("The overbaselineCharge is: "+ overbaselineCharge);

}

else if (kwUsed > 500)

{
baselineCharge=350*basicRate;
overbaselineCharge=150*overBaselineRate;
excessCharge = excessRate * (kwUsed-500);


}

String s = currency.format(baselineCharge + overbaselineCharge + excessCharge);



System.out.print(" " + "Baseline charge " + baselineCharge + " " + "Over-baseline charge" + overbaselineCharge + " "+ "Excess charge");


System.out.print(excessCharge);

//Total bill and Calculating another bill

totalBill= (baselineCharge + overbaselineCharge + excessCharge);

System.out.print(" The total amount due is ");

System.out.printf("%.2f", totalBill);

scan = new Scanner (System.in);

System.out.printf("Calculate another bill? (Y/N)?: ");

choice=scan.next().charAt(0);

}while((choice!='n')&&(choice!='N'));

System.out.println("Thank you for letting us serve you!");
