Answer:
£100.80
Step-by-step explanation:
Lets start with the original price of the tickets.
£12 x 6 = £72
£6 x 3 = £18
£18 + £72 = £90
So now we know the tickets would have cost £90.
We now have to work out how much 10% is.
To do that, we have to divide by 10
90 / 10 = 9
10% = £9
Add that the the ticket cost.
£90 + £9 = £99.
Then we have the 2% for the credit card.
To get 2%, we first have to find 1%, which is found by dividing by 100
90 / 100 = 0.9
1% = 0.90
0.9 x 2 = 1.8
2% = 1.80
Add that to the previous total and there's your answer.
£99 + £1.80 = £100.80
