Word problem

Between the years 1999 and 2003 the average text book rose from $45.00 to $67.00/  What is the percent of increase (rounded to the nearest whole number) for the average text book.

Re: Word problem

Percentage increase = (new amount - old amount)/old amount.

So in this case, it would be (67-45)/45 = 22/45.
Multiply this by 100% to get a percentage and you get an increase of 49% to the nearest whole number.


Why did the vector cross the road?
It wanted to be normal.
