Question

Someone please help me I’ll give out brainliest please dont answer if you don’t know

Answer 1

Answer:

20% decrease

Step-by-step explanation:

Below are the steps that we will follow:

1. Subtract starting value minus final value
2. Divide that amount by the absolute value of the starting value
3. Multiply by 100 to get percent decrease
4. But if the percentage = negative, it means there was an increase and not a decrease.

Now, lets apply it to the problem:

Starting Value: 465 students

Final value: 372 students

Let's do step #1:

465-372 = 93

Now, let's do step #2:

93/465 = 0.2

Now, we can do step #3:

0.2x100 = 20

Step #4 does not apply to us, so we can ignore that.

20% decrease is the answer.

Hope this helps and happy learning! :)

Answer 2

New value =

465 - Percentage decrease =

465 - (20% × 465) =

465 - 20% × 465 =

(1 - 20%) × 465 =

20% decrease

(100% - 20%) × 465 =

80% × 465 =

80 ÷ 100 × 465 =

80 × 465 ÷ 100 =

37,200 ÷ 100 =

372

Hope this helps!
