Question 514106
The cost of gold in the alloy:
{{{ 2.7g }}}
The cost of silver in the alloy:
{{{ 5*(15 - g) }}}
-----------
{{{ ( 2.7g + 5*(15 - g)) / 15 = 164 }}}
{{{ ( 2.7g + 75 - 5g ) / 15 = 164 }}}
{{{ -2.3g + 75 = 15*164 }}}
{{{ -2.3g = 2460 - 75 }}}
{{{g}}} is going to end up negative. I think
you have the price of gold and the
price of silver reversed.
