Final answer:
The linear equation that models the situation is L = 8x + 6y = 192.
Step-by-step explanation:
The linear equation that models the situation is L = 8x + 6y = 192.
In this equation, L represents the total cost of the frames, x represents the number of large frames, and y represents the number of small frames.
The equation represents the constraint that the total cost of the frames should be equal to $192.
