Answer:
£10.35
Explanation:
1) Find the tip
To find the tip the members payed we have to do 27 x 1.15
The reason we are multiplying by 1.15 is that the final amount would be 15% added on the original payment (100%). This means that we have to add 100 and 15 which gives us 115. After this we simply divide it by 100 to get the decimal multiplier
2) Split into 3
As they are splitting the bill 3 ways we have to divide 31.05 by 3
Each person will pay £10.35
Hope this helps, have a lovely day! :)
