Whenever I eat at a restaurant the bill gets handed to me as I work in finance! I've gotten myself confused with how to work out the bill, so just would like to understand this for future.
So, the bill comes to £115 (including tip) and there are 3 people. 1 person would like to pay £10 more than the other 2 people. How can I work out what each person is to pay? If you could please let me know step by step how you get to the answer, it would be greatly appreciated.
Suppose the 2 other people wish to pay £$x$, where $x$ is just a number. Then the other person wants to pay £$x+10$.
In total, then, $x + x + (x+10) = 3x+10$ pounds is payed.
So we need $3x+10=115$. Rearrange (that is, subtract $10$ from both sides and divide by $3$) to get $x = 35$, i.e. the two people should pay £$35$, and the other person £$45$.
Indeed, you can verify that $35+35+45=115$.
