Answer 1

To create a table that displays the monthly cost of the phone plan based on the number of phone lines, we can use the following formula for the total cost:

Total Cost = Flat Cost + (Number of Phone Lines × Cost per Line)

Given:

• Flat Cost = $50
• Cost per Phone Line = $20

Now, let's calculate the total monthly cost for different numbers of phone lines:

1. 0 Phone Lines:

   • Total Cost = $50 + (0 × $20) = $50

2. 1 Phone Line:

   • Total Cost = $50 + (1 × $20) = $50 + $20 = $70

3. 2 Phone Lines:

   • Total Cost = $50 + (2 × $20) = $50 + $40 = $90

4. 3 Phone Lines:

   • Total Cost = $50 + (3 × $20) = $50 + $60 = $110

5. 4 Phone Lines:

   • Total Cost = $50 + (4 × $20) = $50 + $80 = $130

Now we can summarize this information in a table:

| Number of Phone Lines | Monthly Cost | |-----------------------|--------------| | 0 | $50 | | 1 | $70 | | 2 | $90 | | 3 | $110 | | 4 | $130 |

This table correctly displays the monthly cost of the phone plan based on the number of phone lines.
