Answer:
[tex]\%increase = 12\%[/tex]
Step-by-step explanation:
The formula to calculate the percentage of increase is:
[tex]\% = \frac{x_f-x_i}{x_i}*100\%[/tex]
Where
[tex]x_i[/tex] is the initial amount and [tex]x_f[/tex] is the final amount
So:
[tex]\% = \frac{28000-25000}{25000}*100\%[/tex]
[tex]\% = \frac{3000}{25000}*100\%[/tex]
You can write it as:
[tex]\% = \frac{3*1000}{25*1000}*100\%[/tex]
This is:
[tex]\% = \frac{3}{25}*100\%[/tex]
[tex]\%increase = 12\%[/tex]
