In order to find the percent increase, first let's calculate the absolute increase by subtracting the new and old values:
[tex]abs\text{ }increase=52150-50000=2150[/tex]Now, to find the percent increase, let's divide the absolute increase by the old value:
[tex]percent\text{ }increase=\frac{abs\text{ }increase}{50000}=\frac{2150}{50000}=0.043=4.3\%[/tex]Therefore the percent increase is 4.3%.
