They charge $5 per ticket for a child and $12 per ticket for an adult they sell a total of 342 tickets and make a total of $2250 how many of each type of tickets did they sell

the number of children tickets sold 265

the number of adult tickets sold 77

Step-by-step explanation:

Let x represent the number of children tickets sold.

Let y represent the number of adult tickets sold.

They charge $5 per ticket for a child and $12 per ticket for an adult. They were sold for a total of $2250. This means that

5x + 12y = 2250 - - - - - - - - - -1

The total number of tickets sold is 342. This means that

x + y = 342

Substituting x = 342 - y into equation 1, it becomes

5(342 - y) + 12y = 2250

1710 - 5y + 12y = 2250

- 5y + 12y = 2250 - 1710

7y = 540

y = 540/7 = 77

x = 342 - y = 342 - 77

x = 265

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
