Answer:
The cost per adult is $16.
Step-by-step explanation:
Given that:
Total number of children = 20+22 = 42 children
Total number of adults = 2 + 5 = 7 adults
Total cost for both groups = $490
Cost per child = $9.00
Cost of children ticket = 9.00*42 = $378
Cost of adult tickets = 490-378 = $112
This is the cost for 7 adult tickets.
Cost per ticket = = $16
Hence,
The cost per adult is $16.

<h3>What is permutation?</h3>The formula for permutation is given as:
Permutation =
Where:
- n is the total number of objects = 9
- r is the number selected = 3
Substitute into the formula
Permutation =
P( 9, 3) =
P( 9, 3) =
P( 9, 3) = 504 ways
Thus, the number of ways of she can do it is 504 ways
