. A high school currently has a 30% dropout rate. They’ve been tasked to decrease that rate by 20%. Find the equivalent percenta
1 answer:
Answer:
The equivalent percentage point drop = 10%
Step-by-step explanation:
The percentage point change is the difference between the final and initial values.
The percentage change is the difference between the final and initial values
divided by the initial value
It is required to decrease the dropout rate from 30% to 20%
The point change = 20 - 30 = -10 (-ve change ⇒ decrease)
The percentage change = %
So, the equivalent percentage point drop = <u>10%</u>
And the percentage change = <u>33.33%</u>

<h3>Further Explanation </h3>One variable linear equation is an equation that has a variable and the exponent number is one.
Can be stated in the form:
or
ax + b = c, where a, b, and c are constants, x is a variable
We complete the introduction for the task
Bruce retiled his kitchen. Originally, he bought three boxes of tile with the same number of tiles in each. He ran out of tile and had to go back to get three extra boxes of tile. However, he only used two tiles from the last box to finish the job.
Felicia also retiled her kitchen. She bought five boxes of tile with the same number of tiles that were in each as Bruce’s boxes. She also ran out of tile. She had to go back to the store and get an extra five tiles to finish the job.
We can translate those in to expression of One variable linear equation (x = number of tiles)
- Bruce
He bought three boxes ⇒ 3x
He only used two tiles from the last box ⇒ 2x + 2
Total tiles of Bruce used : 3x+2x+2 = 5x+2
- Felicia
She bought five boxes ⇒ 5x
She get an extra five tiles to finish the job. ⇒ 5 tiles
Total tiles of Felicia used : 5x+5
