Elvira is interested in collecting data about how many students use each of the tables during each lunch period. She has recorded some data on Post-It Notes to analyze later. Here are the notes she has recorded: ● Some students are sitting at the front table. (I got distracted by an incident in the back of the lunchroom, and forgot to record how many students.) ● Each of the students at the front table has been joined by a friend, doubling the number of students at the table. ● Four more students have just taken seats with the students at the front table. ● The students at the front table separated into three equal-sized groups. One group remained and all the other students left. ● As the lunch period ends, there are still 12 students seated at the front table. a) Create an equation and solve it to answer the above question. b) If the bullet points were in a different order, would the equation and answer still be the same? Use an example to help explain your answer.
