Question 165564
Let {{{a}}} = pound of almonds needed
Let {{{w}}}= pounds of walnuts needed
Given is
{{{a + w = 40}}}
therefore
{{{w = 40 - a}}}
{{{1.6a + 1.1w = 1.25*40}}}
{{{1.6a + 1.1*(40 - a) = 50}}}
{{{1.6a + 44 - 1.1a = 50}}}
{{{.5a = 50 - 44}}}
{{{.5a = 6}}}
{{{a = 12}}}
{{{w = 40 - a}}}
{{{w = 28}}}
12 lbs of almonds and 28 lbs of walnuts are needed
