A median sized new single family home grew from 2035 ft^{2 }to 2469 ft^{2. What is the percent of increase }
Connor,
You can determine the percentage of increase ( or decrease) by setting up a simple proportion and then cross multiplying. The formula is:
difference between starting point and ending point/starting point = percentage/100 if you plug your numbers into this formula you would have:
434/2035 = x/100
you then cross multiply 2035x = 43400 ( you should be able to take it from here )
you then divide each side by 2035 to determine the value of x
you can use this method for any percentage of change problem
I hope this helps
