Question 1029743
Let {{{ c }}} = the cost / kg of the bananas
{{{ c + .5 }}} = the cost / kg of the oranges
-------------------
{{{ 2c + 3*( c + .5 ) = 16.5 }}}
{{{ 2c + 3c + 1.5 = 16.5 }}}
{{{ 5c = 15 }}}
{{{ c = 3 }}}
and
{{{ c + .5 = 3.5 }}}
-----------------
Bananas cost $3 / kg
Oranges cost $3.50 / kg
---------------------
check:
{{{ 2c + 3*( c + .5 ) = 16.5 }}}
{{{ 2*3 + 3*( 3 + .5 ) = 16.5 }}}
{{{ 6 + 3*3.5 = 16.5 }}}
{{{ 6 + 10.5 = 16.5 }}}
{{{ 16.5 = 16.5 }}}
OK
