members of a nature club participate in an official butterfly count every summer. in summer of 1996 members counted 225 monarch butterflies . in summer of 1997 members counted 234 monarch butterflies. from 1996 to 1997 what was the approximate percent of increase in the number of butterflies counted?
Divide the difference by the original number of butterflies. Multiply the decimal answer by 100 to get the percentage.
To find the approximate percent of increase in the number of butterflies counted from 1996 to 1997, you need to calculate the percentage increase.
Here's how you can do it:
1. Find the difference between the number of butterflies counted in 1997 and 1996.
Difference = Number of butterflies counted in 1997 - Number of butterflies counted in 1996
= 234 - 225
= 9
2. Calculate the percentage increase by dividing the difference by the original value (number of butterflies counted in 1996) and multiplying it by 100.
Percentage Increase = (Difference / Number of butterflies counted in 1996) * 100
= (9 / 225) * 100
= 0.04 * 100
= 4
Therefore, the approximate percent of increase in the number of butterflies counted from 1996 to 1997 is approximately 4%.
