.

Let x be the number of the $16 frames.

Then the number of the $4 frames is 20-x.


Next you write the total money equation

    16x + 4*(20-x) = 152.


Then you simplify this equation and find


    x = %28152+-+4%2A20%29%2F%2816-4%29 = 6.


ANSWER.  6 frames at $16 and the rest 20-6 = 14 frames at $4.

Solved.
