A) Marjam has a goal of taking at least 10,000 steps today. According to her pedometer, she got 2,500 steps in the morning. There are 10 hours left in the day. How many steps will she need to get each hour (assume she walks the same number of steps each hour) for the rest of the day to meet her goal? Solve this problem. Which graph most clearly communicates the solution?

To find out how many steps Marjam needs to take each hour for the rest of the day to meet her goal, first, we need to determine how many steps she has left to reach her goal. Marjam's goal is 10,000 steps, and she has already taken 2,500 steps in the morning. So, she has 10,000 - 2,500 = 7,500 steps left.
Next, we need to divide the number of steps left by the number of hours left in the day to find out how many steps she needs to take each hour. There are 10 hours left in the day, and she needs to take 7,500 steps. So, 7,500 / 10 = 750 steps.
Therefore, Marjam needs to take 750 steps each hour for the remaining 10 hours to meet her goal of 10,000 steps.
The most appropriate graph to communicate this solution would be a number line, which visually represents the steps taken by Marjam with the number of steps increasing as it moves along the line. The number line would start at 2,500 (representing the steps Marjam has already taken) and go up to 10,000 (representing her goal). A marker or arrow can indicate the position of each hour, showing that Marjam needs to reach a certain number of steps in each hour to stay on track towards her goal.
