Answer:
17.75
Step-by-step explanation:
So what we know is that we have to DIVIDE the bill evenly by the amount of people sharing the bill.
> 53.25 / 3 = ?
> 5 - 3 = 2 ( one 3 goes into 5 )
> 23 - 21 = 2 ( seven 3s goes into 23 )
> 22 - 21 = 1 ( seven 3s goes into 22 )
> 15 - 15 = 0 ( five 3s goes into 15 evenly )
> 53.25 / 3 = 17.75
So this should be your result afterwards.
