Diff. / Original amount= % of increase or decrease

V125BC [204]

Answer:

% increase = $\frac{\text{ Increased number -Original number }}{\text{Original number}} \times 100\%$

% decrease = $\frac{\text{ Original number - Decreased number }}{\text{Original number}} \times 100\%$

Step-by-step explanation:

Percentage Increase:

Let there be an original number. If it increased to a certain value we can calculate the percentage increase value with the help of following formula:

% increase = $\frac{\text{ Increased number -Original number }}{\text{Original number}} \times 100\%$

Percentage Decrease:

Let there be an original number. If it decreases to a certain value we can calculate the percentage decrease with the help of following formula:

% decrease = $\frac{\text{ Original number - Decreased number }}{\text{Original number}} \times 100\%$

11. 5x + 5 what does it equal to

Shkiper50 [21]

Answer:

Step-by-step explanation:

Okay this is an odd question, but what i'm thinking is that

first you have

5x+5

To actually be able to solve we have to move the 5 to the other side.

To do this we subtract it.

Making the equation

5x = -5

Then you need to isolate the variable (X)

So divide 5X by 5, and then divide -5/5

Which leaves you with:

x=-1

enrollment in a photography class increased from 25 to 35 students. What was the percent of increase in enrollment?

ElenaW [278]

<u>Answer</u>

40%

<u>Explanation</u>

A parentage value is a value that has been compared to 100.

Percentage = (change in the value)/(the original value) × 100%

= (35-25)/25 × 100%

= 10/25 × 100%

= 40%
