Answer:
21.87... or 29.16
Step-by-step explanation:
6.5% to 72.00 is 4.68. 15% of 72.00 is 10.8. 10.8+4.68 is 15.48. So, we need to do 72.00+15.48 and get 87.48. Since there are 3 friends and yourself, there are 4 people. I might be wrong lol so I included a second answer if they only mean 3 people.
1. 21.87
2. 29.16
