Question 1067977
Let {{{ n }}} = number of games for which
cost to bowl is the same for each alley
--------------------------------------
{{{ C[A] = 1.75 + 2.25n }}}
{{{ C[B] = 2.75 + 2n }}}
---------------------------
Make {{{ C[A] = C[B] }}}
{{{ 1.75 + 2.25n = 2.75 + 2n }}}
{{{ .25n = 1 }}}
{{{ n = 4 }}}
If 4 games are played in each alley,
the cost is the same
---------------------
Here'a a plot of {{{ C[A] }}} and {{{ C[B] }}}
{{{ graph( 500, 500, -3, 7, -2, 15,  2.25x + 1.75, 2x + 2.75  ) }}}
