Final answer:
The correct algebraic expression for the situation where you start with 250 minutes and use 60 minutes per week is '250 - 60w'. The correct answer is option C - 250 - 60w.
Step-by-step explanation:
The correct answer is option C - 250 - 60w. This algebraic expression represents that you start with 250 minutes and talk for 60 minutes (which equals one hour) each week. Here, w stands for the number of weeks. Since you use up 60 minutes of talk time each week, you need to subtract 60 minutes for each week that passes, which is why 60 is multiplied by w, and this product is subtracted from the initial 250 minutes.
To model the situation given, we start with 250 minutes left on the cell phone, and the student talks for an hour per week. We can use the variable w to represent the number of weeks. Since the student talks for an hour each week, the total number of minutes talked is 60w (60 minutes per hour multiplied by the number of weeks).
To find the algebraic expression, we subtract the total minutes talked from the initial minutes left: 250 - 60w.
