$54,000,000 = x ($90,000,000)
*Divide both sides by $90,000,000 to get x by itself
x= .6 or 60%
Answer:
£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
= <em>£100.98</em>
