Given the price of a CD which is $20, increased to $24.
Solution:
In order to find the percent of increase between the prices, subtract the final price with the initial price, then divide the initial price with the difference.
=24 -20
= 4
= 4/20
= 0.2
Change the decimal into percentage by multiplying it with 100
=(0.2)(100)
= 20%
The percent of increase is 20%.
