Question 1136631
{{{ S = 25000 + .65v }}}
(a)
{{{ 45000 = 25000 + .65v }}}
{{{ .65v = 20000 }}}
{{{ v = 30769.23 }}}
$30,769.23 in sales
(b)
Let {{{ n }}} = number of vacuums sold
{{{ 200n = v }}}
{{{ .65v = 20000 }}}
{{{ .65*200n = 20000 }}}
{{{ .65n = 100 }}}
{{{ n = 100/.65 }}}
{{{ n = 153.85 }}}
He needs to sell 154 vacuums
( can't sell part of a vacuum )
