Let +x+ = number of pounds of raisins in
a 10-pound mixture of walnuts and raisins
+10+-+x+ = pounds of walnuts in the mixture
-------------------------
+4.6x+ = value of raisins in the mixture
+7.4%2A%28+10+-+x+%29+ = value of walnuts in mixture
+7.4%2A%28+10+-+x+%29+%2B+4.6x+ = value of walnuts + raisins
