How many artworks can be collected in one quarter? ** 15 x 2 = <<15*2=30>>30 artworks can be collected in one quarter.
How many artworks can be collected in one school year? ** So in one school year, a total of 30 x 4 = <<30*4=120>>120 artworks can be collected.
How many artworks can be collected in two school years? ** Therefore, 120 x 2 = <<120*2=240>>240 artworks can be collected in two school years.
