the company's pricing plan states that usage rate is constant for any number of minutes connected to the internet. In other words, the increase in cost for 10 more minutes of use ( the value that you located above) will be the same whether you increase from 20 to 30 minutes, 30 to 40 minutes, ect. A second wireless access company has a similar method for computing its costs. unlike the first company that lenore was considering, this second company explicitly states its access fee is $0.15 and its usage rate is $0.4 per minute: Total session cost = $0.15 + $0.4 (Number of Minutes). Looking at the graphs of these two phone companies, in what ways does the line that represents this second company's access plan differ from the line that represented the first company's access plan?
