Question 1151668
<br><pre>
          pounds  percent  pounds of chips
          ----------------------------------
 old mix    12      10      .10(12) = 1.2
  added      x     100      1.00(x) = x
          ----------------------------------
 mixture  12+x      25            .25(12+x)</pre>
Make the equation showing the numbers of pounds of chips in the two ingredients and the mixture:<br>
{{{x+1.2 = .25(12+x)}}}
{{{x+1.2 = 3+.25x}}}
{{{.75x = 1.8}}}
{{{x = 1.8/.75 = 2.4}}}<br>
