$102 is your answer.
Explanation:
Okay, so we know that in order to find this out we have to multiply. First, turn the percentage into a decimal, .15 . Then you're going to do .15 * 120.
.15 * 120 = 18.
Now, we have the cost of what will be taken away from the total bill. So , if $120 is the total bill, we will do $120 - 18 which will get us the answer of $102. So that's your answer! I hope this helps! Happy Holidays and stay safe! Best of luck on your work!
