Question 623949
Let {{{ p }}} = the price he pays per apple
{{{ 12p }}} = price for 12 apples
{{{ p - .4p = .6p }}} is price per apple after 40% drop
------------
So, he still wants to spend {{{ 12p }}}  with {{{ .6p }}} = price/apple
Let {{{ n }}} = number of apples he can buy
{{{ 12p = .6p*n }}}
{{{ n = 12p/.6p }}}
{{{ n = 20 }}}
This is {{{ 20 - 12 = 8 }}} more apples than before for the same amount
