In 1991 a baseball hat sold for 15$.In 2001,the sporting goods store sold baseball hats for 28$.find the percent of change from 1991 to 2001 .show work.
+495 Take the number. Save that number. Lets try 40.
Add 13 to your number. So we will get 53.
Divide your new number by your original number. 53/40 = 1.325.
1.325*100% = 132.5%
It would be tremendously easier to answer your question if you gave a starting number.
i. e, WHAT number are you need to know the percent that will increase it by 13?
Hope this helps :)
