Percentage problem of real life

The price of an item decreased by 20% to $200. Then later the price decreased again from $200 to $150. What is the percent of decrease from the original price to the final price of $150?

Solutions

Expert Solution

We first need to find the original price x. The first decrease gives

x - 20% x = 200

0.8 x = 200

x = 200 / 0.8 = 250

The percentage decrease fro the original price 250 to 150 is given by

part / whole = (250 - 150) / 250 = 0.4 = 40%


Decrease 40%
