Question 1104518
Let {{{p}}} = the price which will make
the online deal cheaper
{{{ ( 1 - .15 )*p + 9.95 < p }}}
{{{ .85p + 9.95 < p }}}
{{{ 9.95 < .15p }}}
I can rewrite this from right to left
without changing it
{{{ .15p > 9.95 }}}
{{{ p > 66.33 }}}
The price in the store of $66.36 makes the
online deal cheaper.
-----------------------------------------
check:
In store:
{{{ p =66.34 }}}
On line:
{{{ .85p + 9.95 = .85*66.34 + 9.95 }}}
{{{ 56.39 + 9.95 = 66.34 }}}
-----------------------------------
In store:
{{{ p = 66.35 }}}
on line:
{{{ .85*66.35 + 9.95 = 56.4 + 9.95 }}}
{{{ 66.35 }}}
------------------------------------
In store:
{{{ p = 66.36 }}}
online:
{{{ .85*66.36 + 9.95 = 56.4 + 9.95 }}}
{{{ 66.35 }}}
------------------------------------
The store price has to go up to $66.36
( by my calculations ) for the on line
deal to be cheaper
