Answer:
Adult ticket: $7
Child ticket: $2
Step-by-step explanation:
Set up a system of equations where a represents the cost of one adult ticket and c is the cost of one child ticket:
2a + 3c = 20
a + 4c = 15
Solve by elimination by multiplying the bottom equation by -2:
2a + 3c = 20
-2a -8c = -30
Add them together:
-5c = -10
c = 2
Now, we can plug in 2 as c to find the value of a:
2a + 3c = 20
2a + 3(2) = 20
2a + 6 = 20
2a = 14
a = 7

Simplifying the given expression, it is found that Curtis is correct.
<h3>How to simplify the expression?</h3>
The expression to be simplified is given by:
[4(10) - 3²] + 6(4)
The non-related operations can be solved first, hence:
[4(10) - 3²] + 6(4) = [40 - 9] + 24
For the square, we have to consider that:
- For -x², the negative is not part of the square, hence the result is negative, as - x*x = -x².
- For (-x)², the negative is part of the square, hence the result is positive, as (-x)*(-x) = x².
The first bullet point is the reason that -3² = 9. Then, the simplified expression is completed as follows:
[40 - 9] + 24 = 31 + 24 = 55.
Which means that Curtis is correct.

Just write a equation then plus 10 on each side, then it will be 2x=16 and then find x, so it will be 8 because 2 times 8 equal 16
