Once the anytime minutes are used up, then theycharge a set rate for overage minutes. For this activity, assume you typically will use 575 minutes permonth.1. Research the price of cell phone plans for two different carriers. For each carrier, get pricesfor two different plans that are close to this assumed usage.2. Create a relationship for each plan (an equation) where represents the monthly phone billand where x represents the minutes used beyond the free anytime minutes. Remember toinclude the standard monthly fee in your function. Note: Give each plan a different functionalname,, , to distinguish them from each other.3. Graph each relationship on the following graph. The x-axis will represent total minutes used,and the y-axis the total monthly cost. Note that the cost will be a horizontal line until you gobeyond the free minutes.4. Label each plan on the graph to match the names denoted in Step 2.5. Which plan is the best one for you? Base your decision on the assumed usage.Required ResourcesInternetNotes from classSubmission RequirementsSubmit your written answers to your instructor at the beginning of Week 6.
