Question 1104030
Let {{{ y }}} = total value in dollars
Let {{{ x }}} = number of each type of coin
{{{ y = .05x + .1x + .25x }}}
{{{ y = .4x }}}

check:
suppose the are {{{ 10 }}} of each type
of coin
{{{ y = .05*10 + .1*10 + .25*10 }}}
{{{ y = .5 + 1 + 2.5 }}}
{{{ y = 4 }}}
and
{{{ y = .4x }}}
{{{ y = .4*10 }}}
{{{ y = 4 }}}
OK
