Final answer:
The students at Somerville High School will maintain an average of 3 trees per participant for their service project this month since they are planning for a 0% increase from the previous average.
Step-by-step explanation:
The question from the student at Somerville High School is about calculating the average number of trees planted by participants in a service project this month. Based on the information provided, students planted an average of 3 trees per participant and plan to average 0% more trees per participant for the current month.
When we are talking about a percentage increase of 0%, this means that there is no change from the original amount. Therefore, if students planted an average of 3 trees per participant before, and they are increasing that number by 0%, the average will remain the same this month.
To be clearer, the calculation of percentage increase is typically done by multiplying the original number by the percentage increase divided by 100. In this case:
Original average × (Percentage increase/100) = Change in average
3 trees × (0/100) = 0
Adding this change to the original average:
Original average + Change in average
3 trees + 0 trees = 3 trees
Therefore, the average number of trees per participant that will be planted this month at Somerville High School remains at 3 trees per participant.
