28775 tickets are sold for a football match. Children’s tickets cost £15. The ratio of children to adults is 9:16. If the total ticket sales makes £615785, what is the difference between the price of an adults ticket and a children’s ticket?

Difference = £10

Step-by-step explanation:

Represent adult with A and children with C

Required

Determine the difference in price of both tickets

Convert ratio to fraction

Cross Multiply

Make C the subject

Substitute in

Take LCM

Multiply both sides by 16

Make A the subject

Substitute 18416 for A in

If a children ticket costs £15, then total children tickets cost:

The total sales is given as:

So, the total cost of adult ticket is:

Recall that number of adults is: 18416

So, an adult ticket costs

So, we have that:

Children Ticket = £15

Adult Ticket = £25

The difference is:

Difference = £25 - £15

Difference = £10

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
