Wee-mobile is offering a cell phone family plan for its users. the breakdown of the cost of the plan per month is given below. subscription fee: $100 (one-time cost) unlimited data cost: $40 per line per month unlimited call cost: $10 per line per month unlimited text message cost: $10 per line per month cost of phone: $300 per line the total cost for a 6-month plan for n lines is represented by the expression below. which statement best describes the coefficient of n?

The total cost for a 6-month plan for n lines is represented by the equation:

Cost = 660n + 100

This equation is in the slope intercept form. The coefficient of n represents the slope here.

In the given scenario the slope can be interpreted as the total variable cost for one line for a period of 6 months.

The variable costs are associated with a line are:

1) Unlimited data cost ($40 per month). So for 6 months this cost will be $240

2) Unlimited Call cost ($10 per month). So for 6 months this cost will be $60

3) Unlimited Text Message Cost ($10 per month). For 6 months this cost will be $60.

4) Cost of Phone ($300 per line)

Adding these costs up we get: 240 + 60 + 60 + 300 = $660

Thus, 660 represents the total cost per line for unlimited data, calls, text message and one phone for 6 months. Therefore, option A gives the correct answer.
