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,
[tex]\bold{\text { percentage increase } = \frac{( \text {final count-initial count} }{\text {initial count}} \times 100}[/tex]
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
[tex]\text { percentage increase }=\frac{72-40}{40} \times 100[/tex][tex] = \frac{32}{40} \times 100[/tex]
[tex]=\frac{4}{5} \times 100[/tex]
= 80
Hence percentage increase when Mrs Lay’s Instagram followers went from 40 to 72 is 80%.
