Question

The price of a laptop computer decreased from 475 to 275. What is the percent of decrease in price

Answer 1

First find the difference in prices...

475 - 275 = 200 so the price went down 200 dollars. No we need to find what percentage of 475 is 200.

475 × x = 200
x = 200/475
x = .4211

Now convert to percentage by multiplying by 100 (move decimal 2 places to the right)

.4211 = 42.11%

It is a 42.11% price reduction.
