The average cost per month of a 2- bedroom apartment in graysonwas $625 last year. this year , the average cost is $650.what is the percent of increase from last year to this year?

Average cost of a 2 bedroom apartment in Grayson last year = $625
The average cost of the 2 bedroom apartment in Grayson this year = $650
Increase in average cost of 2 bedroom apartment in Grayson = (650 - 625) dollars
                                                                                                   = 25 dollars
Then
Percentage increase in average cost = (25/625) * 100
                                                             = 2500/625
                                                             = 4 percent
Average increase in price of the 2 bedroom apartment from last year to this year is 4%. I hope this is the answer you were looking for and the procedure is also clear to you.
