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.
Solution:
Two trains are moving in opposite direction with Speed 40 kmph and 60 kmph. Make train B stationary and then take the Speed of train A relative to the train B. So relative Speed of train A = 40 + 60 = 100 kmph. Before it crashes into the stationary train B it has to travel a Distance of 200 m which it will do in (0.2/100 ) hours. During this duration, the average Speed of bird has been 10 kmph i.e. before the crash total Distance covered by the bird = 0.2 * 10/100 km = 20 meters.
