Question 13219
First find the amount of increase.  Since the income went from $32000 to 48000, this means that the amount of increase is $16000.  Percent of increase is always a comparison of the amount of increase to the ORIGINAL amount, which is $32000.  


Percent of increase = {{{ (Amount Increase)/ Original Amount) }}}
= {{{ 16000/32000}}}    = {{{1/2}}} = 50%
