Does anyone know how to do
a store is having a sale on chocolate chips and walnuts. for 3 pounds of chocolate chips and 2 pounds of walnuts, the total cost is $13. for 8 pounds of chocolate chips and 4 pounds of walnuts, the total cost is $33. find the cost for each pound of chocolate chips and each pound of walnuts.
cost of each pound of chocolate chips: $
cost for each pound of walnuts: $

Cost of a pound of chocolate chips: $3.5

Cost of a pound of walnuts: $1.25

Step-by-step explanation:

x - cost of a pound of chocolate chips

y - cost of a pound of walnuts

We create two equations based on the information we have:

3x+2y=13

8x+4y=33

The whole point of these problems os to get rid of x or y. In this question, we can do this by multiplying both sides of the first equation by 2, and then subtracting it from the second equation:

8x+4y=33

6x+4y=26

2x=7

x=3.5

Then we change x for 3.5 in the first equation:

3×3.5+2y=13

10.5+2y=13

2y=2.5

y=1.25

Hope this helps!

step-by-step explanation:

if x = 2 you have to find x to finish the problem
