this is a mixture problem
Let P be the pounds of Pecans
and A be the pounds of almonds.
P+A=15 (given)
now, the cost: 3.5*P is the cost of pecans, and 5*A is the cost of almonds, then the sum of costs equals total cost.
3.5P+5A=4*15
So now, you know A=15-P so
3.5P+5(15-P)=4*15 and you solve for P, pounds of Pecans. Then go back and solve for A, since A=15-P
