The second sentence tells us that cell phone plan charges a base fee of $62 so we can substitute this “A ....” specific information into our general equation and we have We can eliminate answer choices and The correct answer is either or d. a b. c The second sentence also tells us that the overage charge is per gigabyte of data that exceed 2 “...$30 We can use this information to choose between answer choices and c d. gigabytes.” Answer choice is . This make sense, because the value of the term becomes negative if the c doesn’t number of gigabytes used is greater than 2, and the total cost becomes negative if the number of gigabytes used is 5 or more. Answer choice c can be eliminated. Answer choice d is the only choice left, and is the correct answer. DIMS? Does It Make Sense? Yes. could represent the plan as when more than 2 gigabytes are used, shown in the following table of values for this function.. PTS: 2 NAT: A.CED.A.1 TOP: Modeling Linear Functions
