Last school year, there were 540 students in 7th grade at our school. This year, there are 495 7th graders. Find the percent of change. State whether the change is an increase or decrease.
Answer: The change is for sure a decrease since you have less 7th graders. the percent decrease is 8.3333 (the threes continue on for a while, you could also round down to cancel that —> 8.32)
