Question 613864
{{{ C(x) = m*x + b }}}
given:
{{{ C(0) = 12500
{{{ C(0) = m*0 + b }}}
{{{ 12500 = b }}}
and
{{{ C(3) = 14450 }}}
{{{ C(3) = m*3 + 12500 }}}
{{{ 14450 = m*3 + 12500 }}}
{{{ 3m = 14450 - 12500 }}}
{{{ 3m = 1950 }}}
{{{ m = 650 }}}
-----------
{{{ C(x) = 650x + 12500 }}}
Here's a plot where {{{ C(x) }}} is in thousands of dollars
