As part of an ongoing service project, the students at Millersburg High School recently spent an afternoon planting trees. They planted an average of 6 trees per participant. Soon they plan to do some more planting, averaging 9 trees per participant. If everything goes as planned, what will be the percent of increase in the average number of trees planted?

There is a 50% increase in the average number of trees planted at the high school

Step-by-step explanation:

in this question, we are asked to calculate the percentage increase in the average number of trees planted at a high school.

To calculate this, firstly we need to know the old average number of trees planted and the new average number of trees planted. This is already given in the question as 6 and 9 respectively.

Hence, mathematically,

the percentage increase = (new average value - old average value) / old average value * 100

= (9-6) / 6 * 100

3/6 * 100

= 50%
