£25.60

Step-by-step explanation:

The cost of the adult ticket is reduced by 1/3, so the price paid for one adult ticket with the discount is 24 * (1 - 1/3) = 24 * (2/3) = £16.

Two child tickets would normally cost 2 * 12 = £24, but their prices are reduced by 60%. 60% is equivalent to 60/100, or simplified, 3/5. So the price of the two child tickets with the discount would be 24 * (1 - 3/5) = 24 * (2/5) = £9.60.

Adding the discounted adult ticket price to the discounted price of the two child tickets, we get 16 + 9.60 = £25.60 as the total price.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
