Final answer:

To solve this problem, you can use a system of equations. The group consists of 3 adults and 5 kids.

Step-by-step explanation:

To solve this problem, we can use a system of equations. Let's represent the number of adults as 'A' and the number of kids as 'K'. We know that there are 8 people in total, so we have the equation A + K = 8. We also know that the cost of tickets for adults is $6 and for kids is $3, and they paid a total of $33. This gives us the equation 6A + 3K = 33.

We can solve this system of equations by substitution or elimination. For simplicity, let's use substitution. From the first equation, we can rewrite K as K = 8 - A. Substituting this into the second equation, we get 6A + 3(8 - A) = 33.

Simplifying the equation, we get 6A + 24 - 3A = 33. Combining like terms, we have 3A + 24 = 33. Subtracting 24 from both sides, we get 3A = 9. Dividing both sides by 3, we find A = 3.

Now that we know there are 3 adults, we can plug this into the first equation to find K. A + K = 8, so 3 + K = 8. Subtracting 3 from both sides, we get K = 5. Therefore, there are 3 adults and 5 kids in the group.

Number of kids is 5 and number of adults is 3.

Step-by-step explanation:

  • Step 1: Let the number of adults be x. Then the number of kids is (8-x). Cost of tickets for adults = 6x

Cost of tickets for kids = 3(8-x) = 24 - 3x

Total cost = 33 = 6x + 24 - 3x = 3x + 24

⇒ 3x = 9

x = 3

⇒ 8 - x = 8 - 3 = 5

∴ Number of kids is 5 and number of adults is 3.
