Question

Mrs. Lay's Instagram followers went from 40 to 72. What was the percent increase?

Answer 1

Answer:  

The percentage increase when Mrs.Lay’s instagram followers went from 40 to 72 is 80%

Solution:

The percentage increase can be found out by dividing change in value by initial value. This is given as,

$\bold{\text { percentage increase } = \frac{( \text {final count-initial count} }{\text {initial count}} \times 100}$

From question, we get

Initial count of Mrs.Lay = 40

Final value of Mrs.Lay = 72

So percentage increase when Mrs Lay’s Instagram followers went from 40 to 72 is

$\text { percentage increase }=\frac{72-40}{40} \times 100$$= \frac{32}{40} \times 100$

$=\frac{4}{5} \times 100$

= 80  

Hence percentage increase when Mrs Lay’s Instagram followers went from 40 to 72 is 80%.
