Increase rate per week = 25%
Now,
Increase of followers by 3 weeks will be,
= 25% × 3
= 75%
Number of follower = 45000
To Find:
Total number of followers after 3 weeks = ?
Solution:
Now,
Increase in number of followers = Number of % followers + Number of followers × 75/100
On putting the values in the above formula, we get
= 45000+(45000\times \frac{75}{100} )45000+(45000×
100
75
)
= 45000+(450\times 75)45000+(450×75)
= 45000+3375045000+33750
= 7875078750
Thus, after 3 weeks, the total number of followers will be "78750".
