Hello!
First, you'll need to find 20% of 150. You can do this by converting 20% into a decimal. To do so, you'll need to move the decimal place twice to the left to get 0.20. Now you'll need to multiply 150 by 0.20. Once you've done that, you should get $30. Now to find how much Romy paid in total, you'll need to add $30 to $150.
Romy in total payed $180 for the bill
I hope this helps!
