Work out total charge that Cheryl will play if she uses her credit card to buy the tickets Please can I have help asap

£100.98

Step-by-step explanation:

Step 1: find total price of tickets

Total price of tickets = 6 adults (£12) + 3 child (£6) = 6(12) + 3(6)

= 72 + 18

Total of tickets = £90

Step 2: Find the extra added 10% booking fee

Booking fee added = 10% of £90

= 10/100 × 90

= 0.1 × 90

Adding booking fee = £9

Step 3: Calculate the added 2% that would be added for using credit card

Cheryl would be paying £99 with her credit card (price of tickets + added booking fee = £90 + £9)

2% of £99 = 2/100 × 99

Added credit card charges = 0.02 × 99 = £1.98

Step 4: Calculate the total charge to be paid by Cheryl if she uses her credit card for the payment

Total charge = cost of tickets + added booking fee + credit card charges

= £90 + £9 + £1.98

= £100.98
