Tickets to a play are priced as follows:
Adult tickets: £12
Child tickets: £6
Cheryl rings the booking office to buy 6 adult tickets and 3 child tickets.
She is told that a 10% booking fee will be added to the ticket price. 2% then will be added if she is paying by credit card.
Work out the total charge that Cheryl will pay if she uses her credit card to buy the tickets.

She has to pay £100.98.

Step-by-step explanation:

Given,

The cost of adult ticket = £12

The cost of child ticket = £6

10% booking fee will be added.

2% will be added if she is paying by credit card.

Number of adult = 6

Number of child = 3

To find the cost of ticket if she uses her credit card.

Formula

If a% increases on b the value will be = b×

Total cost of the ticket =  £12×6+£6×3 = £90

After 10% booking fee = £90× = £99

After paying by her credit card 2% = £99× = £100.98

Hence,

She has to pay £100.98.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
