Answer :
Data
• Original price: $2.40
,• Increased price: $2.65
Procedure
As $2.40 is our original price, this represents 100% of our data. The increased price will be more than 100%, and this will be our percentage increse. To calculate this, we have to build the following relation:
[tex]\frac{2.40}{100}=\frac{2.65}{x}[/tex]where x is the percentage we want to know. Solving for x:
[tex]x=\frac{2.65}{2.40}\cdot100[/tex][tex]x=110.4[/tex]As 100% is the original percentage price, then the percentage increase is:
[tex]x=110.4-100=10.4[/tex]Answer: 10.4%
