IrinaVladis [17]

Answer:

The total charge for these tickets when paying by credit card is £ 90.64.

Step-by-step explanation:

Since Billy wants to buy 4 adult tickets at £ 15 each and 2 child tickets at £ 10 each for a show, and a 10% booking fee is added to the ticket price, and 3% is then added for paying by credit card, for work out the total charge for these tickets when paying by credit card the following calculation must be performed:

((4 x 15 + 2 x 10) x 1.10) x 1.03 = X

((60 + 20) x 1.10) x 1.03 = X

(80 x 1.10) x 1.03 = X

88 x 1.03 = X

90.64 = X

Thus, the total charge for these tickets when paying by credit card is £ 90.64.
