Question 1090945
Let {{{ C }}} = the cost for {{{ n }}} visits
(1) {{{ C = 1000 + 500n }}}
(2) {{{ C = 700n }}}
---------------------------
Set the costs equal to eachother
{{{ 1000 + 500n = 700n }}}
{{{ 200n = 1000 }}}
{{{ n = 5 }}}
At 5 visits the costs are equal
-------------------------------
check:
(1) {{{ C = 1000 + 500*5 }}}
(1) {{{ C = 3500 }}}
and
(2) {{{ C = 700*5 }}}
(2) {{{ C = 3500 }}}
OK
