Question 1108375
Compare the costs, {{{ C }}}
Let {{{ n }}} = number of fitness classes
{{{ C[1] = 4n + 300 }}}
{{{ C[2] = 2n + 360 }}}
----------------------------
Set {{{ C[1] = C[2] }}}
{{{ 4n + 300 = 2n + 360 }}}
{{{ 2n = 60 }}}
{{{ n = 30 }}}
----------------------------
After 30 classes, the costs are the same
check:
{{{ 4*30 + 300 = 2*30 + 360 }}}
{{{ 420 = 420 }}}
OK
