There are 15 students in the art club. By the end of each quarter, each student makes two artworks. If there are four quarters in a school year, how many artworks can the art club collect in two school years?
15 x 2 = <T>multiply(15, 2)=30 artworks can be collected in one quarter.
So in one school year, a total of 30 x 4 = <T>multiply(30, 4)=120 artworks can be collected.
Therefore, 120 x 2 = <T>multiply(120, 2)=240 artworks can be collected in two school years.
