The middle school student has 10 cups of confetti to decorate the tables for the banquet. They plan to use 1/3 cup of confetti on each table. If they use 1/4 cup of confetti on each table instead of 1/3 cup of confetti, how many more tables can the decorate?

Answer 1

With 1/3 cup of confetti at each table, the student will decorate 10/(1/3) = <<10/(1/3)=30>>30 tables.
With 1/4 cup of confetti at each table, they can decorate 10/(1/4) = <<10/(1/4)=40>>40 tables.
Thus, they can decorate 40-30= <<40-30=10>>10 more tables. Answer: \boxed{10}.
