## mskyeg 2 years ago A food store makes a 11–pound mixture of peanuts, almonds, and raisins. The cost of peanuts is \$1.50 per pound, almonds cost \$3.00 per pound, and raisins cost \$1.50 per pound. The mixture calls for twice as many peanuts as almonds. The total cost of the mixture is \$21.00. How much of each ingredient did the store use?

In our school we had the exact same situation, ill give it a short try however, dont expect any explanations. btw I got it wrong. this is how I think I would solve it though.

3. HyperChemist

11x=p1.50+a3.00+r1.50,

4. HyperChemist

21\$=p1.50+a3.00+r1.50

8. HyperChemist

21\$=p1.50+a3.00+r1.50 11p, ,6,3,3

whenver I try to multiply it, it gives me a bigger number, therefoe this means that the amound of almonds is smaller then the amount of raisins, therfore giving a bigger value, however I do not know how to find what value would make this work... I trie,d and thanks for wating...
