230 to 253 is a 10% increase. True or false?

Answer:
True

Explanation:
To get the percent of increase, we will use the following equation:
% of increase = [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 = [tex] \frac{253-230}{230} *100[/tex]

% of increase = 10%

Therefore, the given statement is correct

Hope this helps :)
