In this question, it is given that p represents cost of 1 container of popcorn. Therefore cost of 5 containers of popcorn = 5p and cost of 3 containers of popcorn = 3p.

And g represents cost of 1 container of granola bars. THerefore cost of 4 containers of granola bars = 4g and cost of 6 containers of granola bars = 6g.

According to the given question, the required linear equations are

5p+4g=42.50, 3p+6g = 34.50.

And these are the the required system of linear equation.
