24.Ramon is a waiter. He waits on a table of 4 whose bill comes to $109.98. If Romon receives a 15% tip, approximately how much will he receive？

（不知道是不是用这个↓）

25.Nicole sold 15 tickets to the school play and Andrew sold 18 tickets. What is the ratio of the number of tickets Nicole sold to the number of tickets Andrew sold?

（注：ratio是比率）

还有公式是 i=prt

要写出过程 谢谢~

1. 第一个是你说的公式 part/109.98=15/100，part=16.497（看你要保留几位小数了）

2.Nicole/Andrew=15/18=5/6
