A candy store sells 8 pound bags of mixed almonds and cashews. If c pounds of cashews are in a bag,...

c=1 was already given as described. The store sells pound bags.

The rest of the description and question seem not to match. Maybe each bag contains 8 pounds of the two nuts. Eight pounds and some of this is of cashews. Now, c is how many pounds of cashews in one bag.

p=2.59%2Ac%2B1.72%288-c%29
You want to know the quantity of cashews if p=18.11 dollars per bag.
2.59c%2B1.72%2A8-1.72c=p
2.59c-1.72c=p-1.72%2A8
%282.59-1.72%29c=p-1.72%2A8
0.87c=p-13.76
highlight_green%28c=%28p-13.76%29%2F0.87%29-------plug in p=18.11.
