Explanation: To get the percent of increase, we will use the following equation: % of increase =Β [tex] \frac{"new"value-"old"value}{"old"value} *100[/tex]
In the given we have: new value = 253 old value = 230
Substitute in the above equation to get the % of increase as follows: % of increase =Β [tex] \frac{253-230}{230} *100[/tex]
