A mathematics magazine which usually cost P 15 is now sold at P 18.
What percent was the increase?

Sagot :

To find the percent increase, divide P 18 by P 15
P 18 divided by P 15=1.2

Convert to percent by multiplying 100
1.2 x 100=120%

Hope this helps =)

Since we are looking for the rate of increase:
[tex]Rate= \frac{Percentage}{Base} = \frac{18-15}{15} = \frac{3}{15} =0.2=20[/tex]%
