<PRE><B>Question 573500</B>
Let {{{ x }}} = number of games bowled 
Let {{{ p }}} = price of bowling
Wedge St:
{{{ p = 5.5 + 2.5x }}}
Lawrence St:
{{{ p = 4 + 3x }}}
--------------
If  prices at both alleys are equal:
{{{ 5.5 + 2.5x = 4 + 3x }}}
{{{ .5x = 1.5 }}}
{{{ x = 3 }}}
4 games bowled will make Wedge St cheaper
check:
3 games bowled:
{{{ p = 5.5 + 2.5*3 }}}
{{{ p = 5.5 + 7.5 }}}
{{{ p = 13 }}}
and
{{{ p = 4 + 3*3 }}}
{{{ p = 13 }}}
4 games bowled:
{{{ p = 5.5 + 2.5*4 }}}
{{{ p = 5.5 + 10 }}}
{{{ p = 15.5 }}}
and
{{{ p = 4 + 3*4 }}}
{{{ p = 16 }}}
Wedge St is cheaper
