you have 50 students one day and 70 the next what is the percentage increase
I think it is 20%. Because a each tenth is 10% and 70-50 equals a 20% increase. so i'm sure its 20%
Sorry, but Environmental is wrong.
70-50 = 20 student increase
20/50 = 0.4 = 40% increase
To find the percentage increase between two values, you can use the following formula:
Percentage Increase = (New Value - Old Value) / Old Value * 100
In this case, the old value is the number of students on the first day, which is 50, and the new value is the number of students on the second day, which is 70.
Let's substitute the values into the formula:
Percentage Increase = (70 - 50) / 50 * 100
Simplifying the formula:
Percentage Increase = 20 / 50 * 100
Percentage Increase = 0.4 * 100
So, the percentage increase is 40%.
