How the Calculation Works

The calculator uses a simple formula:

• Number of Lines: 3
• Add-ons: $10 per line

Step-by-step breakdown:

• Base cost: 85 × 3 = 255
• Add-ons: 10 × 3 = 30
• Subtotal: 285
• Discount (10%): 28.50
• Final total: 256.50

Results:

• Total Monthly Bill: $256.50
• Per Line Cost: $85.50
