Hi there:

I hope I get help with it, thnx

private void totalButton_Click(object sender, EventArgs e)

{

decimal foodChargeAmount; // The amount of food charge.

decimal tipPercentage, tipAmount; // The tip percentage & amount.

decimal saleTaxPercentage, saleTaxAmount; // Sale tax percentage & amount.

decimal totalAmount; // The total amount.

// Assigning food charge amount from TextBox control to respective variable.

foodChargeAmount = decimal.Parse(foodChargeTextBox.Text);

// We will assign the tip percentage as 15.

tipPercentage = 15;

// Tip amount calculation.

tipAmount = tipPercentage * (foodChargeAmount / 100);

// Assigning sales tax percentage as 7.

saleTaxPercentage = 7;

// Sales tax percentage calculation.

saleTaxAmount = saleTaxPercentage * (foodChargeAmount / 100);

// Total amount calculation.

totalAmount = (foodChargeAmount + tipAmount + saleTaxAmount);

resultLabel.BorderStyle = BorderStyle.FixedSingle;

resultLabel.ForeColor = Color.Tomato;

// The result label will display (Food charge + tip percentage + sale tax percentage + total amount).

resultLabel.Text = "Food Charge for a meal is:" +

foodChargeAmount.ToString("c") + "";

resultLabel.Text = "The tip percent for a meal is:" +

tipAmount.ToString("c") + "";

resultLabel.Text = "Sales tax percentage for a meal is:" +

saleTaxAmount.ToString("c") + "";

resultLabel.Text = "The total amount is"+

totalAmount.ToString("c") + "";

}

}

}

Explanation / Answer

Solution:

you need to display (Food charge + tip percentage + sale tax percentage + total amount using result label.

So combine all these answers as single string and assign that string value to the result label text.

Modified program:

private void totalButton_Click(object sender, EventArgs e)
{
decimal foodChargeAmount; // The amount of food charge.
decimal tipPercentage, tipAmount; // The tip percentage & amount.
decimal saleTaxPercentage, saleTaxAmount; // Sale tax percentage & amount.
decimal totalAmount; // The total amount.

// Assigning food charge amount from TextBox control to respective variable.
foodChargeAmount = decimal.Parse(foodChargeTextBox.Text);
// We will assign the tip percentage as 15.
tipPercentage = 15;
// Tip amount calculation.
tipAmount = tipPercentage * (foodChargeAmount / 100);
// Assigning sales tax percentage as 7.
saleTaxPercentage = 7;
// Sales tax percentage calculation.
saleTaxAmount = saleTaxPercentage * (foodChargeAmount / 100);
// Total amount calculation.
totalAmount = (foodChargeAmount + tipAmount + saleTaxAmount);
resultLabel.BorderStyle = BorderStyle.FixedSingle;
resultLabel.ForeColor = Color.Tomato;
// The result label will display (Food charge + tip percentage + sale tax percentage + total amount).

String answer="Food Charge for a meal is:"+foodChargeAmount.ToString("c") + ".The tip percent for a meal is:" +
tipAmount.ToString("c") + ". Sales tax percentage for a meal is:" + saleTaxAmount.ToString("c") + ". The total amount is"+
totalAmount.ToString("c") + "";

resultLabel.Text =answer;
}
}
}
