Question

During the course of a year, the price of a house increased from $200,000,000 to $250,000. What was the percent increase in price?

Answer 1

The equation for percent increase is: (x-y)/y, where x is the final price and y is the beginning price.
So for this problem we substitute to get:
(250000-200000) / 200000
We subtract the 200000 to get:
50000 / 200000
We divide by 200000 to get: .25
We can convert this to percent by multiplying by 100. We get: 25%
Hope this helps.
