Question 80782
Let's denote:

1 Chocolate bar = b

1 Pack of Gum = g

Now, let's express Sally's and Jake's purchases with these variables.

3b + g = 1.75 ----(1)

2b + 4g = 2.00 ---(2)

So now we have a system of two equations.

Do you know how to solve for variables in a system of equations? If you don't, please write back.
