Tickets to a play are priced as follows: adult-£12 and child:£6

Cheryl rings the booking office to but 6adult tickets and 3child tickets. she is told that a 10% booking fee will be added to the ticket price. 2% will then be added if she is paying by credit card. work out the total charge that Cheryl will pay after she uses the credit card to buy the tickets?

Cheryl has to pay a total charge of £100.98.

Step-by-step explanation:

Step 1; A ticket for an adult costs £12 and a ticket for a child costs £6. So for 6 adults and 3 children, the ticket price is

Ticket price = 6 * £12 + 3 * £6 = £72 + £18 = £90.

So the ticket prices alone are £90. A booking fee of 10% is added to this £90.

Booking fee = 10% of £90 = £9.

Ticket price inclusive of booking fee = £90 + £9 = £99.

Step 2; Cheryl pays by credit card so an additional 2% is added to the final price i. e. 2% is added to the £99.

Credit card charges = 2% * £99 = £1.98

Final booking fee = £99 + £1.98 = £100.98.

So buying the tickets with credit card, Cheryl pays £100.98 to buy the tickets.
