Respuesta :

Answer:

23,180 pieces

Explanation:

The number of white paper used = 13,480 pieces

Since they used 7,880 fewer pieces of blue paper than white paper

The number of blue paper used = 13,480 - 7880 =5,600 pieces

They also used 1,500 fewer pieces of yellow paper than blue paper.

The number of yellow paper used = 5,600-1500 =4100 pieces

Therefore. the total number of pieces of paper

=13,480 + 5,600 + 4100

=23,180 pieces
