Noor brought 212121 sheets of stickers. She gave \dfrac{1}{3} 3 1 start fraction, 1, divided by, 3, end fraction of a sheet to each of the 454545 students at recess. She wants to give teachers 1\dfrac{1}{2}1 2 1 1, start fraction, 1, divided by, 2, end fraction sheets each. Which inequality describes the number of teachers, ttt, Noor could give sheets of stickers to? Choose 1 Choose 1 (Choice A) A 15+\dfrac{3}{2}t>2115+ 2 3 t>2115, plus, start fraction, 3, divided by, 2, end fraction, t, is greater than, 21 (Choice B) B 15+\dfrac{3}{2}t\geq 2115+ 2 3 t≥2115, plus, start fraction, 3, divided by, 2, end fraction, t, is greater than or equal to, 21 (Choice C) C 15+\dfrac{3}{2}t<2115+ 2 3 t<2115, plus, start fraction, 3, divided by, 2, end fraction, t, is less than, 21 (Choice D) D 15+\dfrac{3}{2}t\leq 2115+ 2 3 t≤2115, plus, start fraction, 3, divided by, 2, end fraction, t, is less than or equal to, 21 What is the solution set of the inequality?
