Question 1025525
Let {{{ x }}} = hotel charge before tax in 1st city
{{{ x - 1500 }}} = hotel charge before tax in 2nd city
------------------
{{{ .055x + .075*( x - 1500 ) = 570 }}}
{{{ .055x + .075x - 112.5 = 570 }}}
{{{ .13x = 682.5 }}}
{{{ x = 5250 }}}
{{{ x - 1500 = 3750 }}}
-------------------------
$5250 = hotel charge before tax in 1st city
$3750 = hotel charge before tax in 2nd city
------------------
check answer:
{{{ .055x + .075*( x - 1500 ) = 570 }}}
{{{ .055*5250 + .075*3750 = 570 }}}
{{{ 288.75 + 281.25 = 570 }}}
{{{ 570 = 570 }}}
OK
