ts. there are _______ adults in that group and _______ kids. can someone explain how to solve this in words for an essay.
1 answer:
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.
