 <translate> Ten students raised a total of $20 x 10 = $200. There are 30 - 10 = 20 students who raised $30 each. Twenty students raised a total of $30 x 20 = $600. Therefore, the students raised a total of $200 + $600 = $800. So, the answer is 800. <yor> Àwọn akẹ́kọ̀ọ́ mẹ́wàá kó àpapọ̀ owó tó lé ní $20 x 10 = $200 jọ. Àwọn akẹ́kọ̀ọ́ 30 - 10 = 20 ló kó $30 jọ.
