Question 1042637
The "rate" the apples are selling at is:
{ b cents ] / [ x apples ], or
{{{ b/x }}} cents/apples
----------------------
If you multiply the "rate" by the number of apples
You get the cost of that many apples, so
{{{ (b/x)*y }}} = {{{ b*( y/x ) }}}
------------------------
[ cent / apples ] x [ apples ] = [ cents ]
so, the dimensions make sense
