Question

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

Answer 1

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}} * 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 }=(72-40)/(40) * 100`
`= (32)/(40) * 100`

`=(4)/(5) * 100`

= 80

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