Question 779147
( cost of shirt ) / ( cost of jacket ) = {{{ 2/5 }}}
Let {{{ c }}} = the cost of the shirt
{{{ c + 240 }}} = the cost of the jacket
-----------------
Now I can say:
{{{ 2/5 = c / ( c + 240 ) }}}
Multiply both sides by {{{ 5*( c + 240 ) }}}
{{{ 2*( c + 240 ) = 5c }}}
{{{ 2c + 480 = 5c }}}
{{{ 3c = 480 }}}
{{{ c = 160 }}}
{{{ c + 240 = 400 }}}
The shirt costs $160
The jacket costs $400
