Question 990462
In words:
[ price / weight ] x [ weight of product bought ] = [ price paid for product bought ]
-----------------------
Say 100 pounds of yogurt is bought
price paid = {{{ ( 1.6 / ((1/4) ))*100 }}}
---------------------------------
The way to deal with {{{ 1.6/((1/4)) }}} is
multiply top and bottom by {{{ 4 }}}
{{{ 1.6 / ((1/4)) = 6.4 / 1 }}}, so
 {{{ ( 1.6 / ((1/4)) )*100 = 6.4*100 }}}
{{{ 6.4*100 = 640 }}}
$640 is paid for 100 pounds of yogurt
-----------------------------------
Instead of 100 pounds, use whatever weight you want
