Math is very useful when splitting a check. Especially when it's you and 5 friends. Let's say we go to a steak house. The total comes to $210 which is 35 each person.We would like to tip at least 25% when going out to something like a steakhouse. So that's 210x0.25=52.5. So the total with tip is 52.5+210 which equals $262.50. This semester, we discussed addition, division, and percentage. These skills make it so everything is fair and split, while also giving the server a good tip. reply in 50 words
