Question

A candy store sells 8-pound bags of mixed hazelnuts and cashews. If c pounds of cashews are in a bag, the price p of the bag can be found using the formula p= 2.59c + 1.72(8-c). If one bag is priced at $18.11, how many pounds of cashews does it contain

Answer 1

C= how many pounds of cashews in a bag
P=how much the cost
Solve for C
we know that P would have to be $18.11
Sub wat P= to in the equation
$18.11=2.59c+1.79(8-c)
Start with multiplying
1.79(8)=14.32(c)=14.32c
Then add like terms
2.59c+14.32c=16.91c
Divide to get C by itself. So that 16.91 cancel itself.
16.91c/16.91c=18.11/16.91
C=1.07
I might be wrong but I tried so wateves
