Question

Veronica has a cell phone plan where she pays $29.90 per month for unlimited calls and up to 500 text messages. However, if she goes over her allowance of text messages, she is charged an additional fee of $0.10 apiece. Her cell phone bill can be modeled by the function , where x represents the number of text messages over 500. Given the graph of , which state?

a) She used exactly 500 text messages.
b) She used more than 500 text messages.
c) She didn't use any text messages.
d) The graph does not provide enough information to determine the state.

Answer 1

Without the graph of the function which models Veronica's cell phone bill, it is not possible to determine how many text messages she used. The correct answer to the student's question is d) The graph does not provide enough information to determine the state.

Step-by-step explanation:

The question given seems to include irrelevant details that aren't directly related to solving the student's query about Veronica's cell phone plan. Here's the core information we need to consider: Veronica pays $29.90 per month for unlimited calls and up to 500 text messages. If she sends more than 500 text messages, each additional message costs $0.10. We assume the student is referring to a function like f(x) = 29.90 + 0.10x, where x is the number of texts over the 500 message limit. To address the actual question, we need a graph of this function to analyze it, which isn't provided. Without the graph, we cannot determine whether she used exactly 500 text messages, more than 500, or none. Therefore, choice d) The graph does not provide enough information to determine the state, would be the correct answer.
