Math Problem Statement

A store is having a sale on walnuts and chocolate chips. For 3 pounds of walnuts and 5 pounds of chocolate chips, the total cost is $16. For 6 pounds of walnuts and 2 pounds of chocolate chips, the total cost is $22. Find the cost for each pound of walnuts and each pound of chocolate chips.

Solution

The problem in the image can be summarized as follows:

A store is having a sale on walnuts and chocolate chips.

  • For 3 pounds of walnuts and 5 pounds of chocolate chips, the total cost is $16.
  • For 6 pounds of walnuts and 2 pounds of chocolate chips, the total cost is $22.

We are tasked with finding the cost for each pound of walnuts and each pound of chocolate chips.

Let:

  • xx = the cost of one pound of walnuts.
  • yy = the cost of one pound of chocolate chips.

From the problem, we can form the following system of equations based on the given information:

  1. 3x+5y=163x + 5y = 16 (from the first scenario)
  2. 6x+2y=226x + 2y = 22 (from the second scenario)

Now, I will solve this system of equations to find the values of xx and yy.It seems like I can’t do more advanced data analysis right now. Please try again later.
