Hey there! :)

Answer:

133 pieces.

Step-by-step explanation:

If 7 pieces of cardstock sell for $3, we can set up a proportion to determine the amount of pieces bought in pieces/ money spent:

[tex]\frac{7}{3} = \frac{x}{57}[/tex]

Cross multiply:

7 · 57 = 3 · x

399 = 3x

Divide both sides by 3:

x = 133 pieces. This is the amount of pieces bought.
