Answer:
$15
Step-by-step explanation:
This question can be solved with the use of a system of equations.
Start by defining the variables that will be used:
Let the cost of 1 adult and 1 child to attend the show be $a and $c respectively.
Form 2 equations and label them:
a +2c= 35 -----(1)
2a +3c= 60 -----(2)
Let's solve by elimination. Since the question is only asking for the cost for an adult to attend the show, we can work to eliminate the c term. This can be done by ensuring that the coefficients of c in both equation has the same numerical value (the sign does not really matter for now). In this case, we can make the coefficient of c to be 6 since it is the lowest common multiple of 2 and 3.
(1) ×3: 3a +6c= 105 -----(3)
(2) ×2: 4a +6c= 120 -----(4)
Since the coefficient of c in both (3) and (4) are +6, we can subtract one equation from the other to eliminate the term c.
(4) -(3):
(4a +6c) -(3a +6c)= 120 -105
Expand:
4a +6c -3a -6c= 15
a= 15
Thus, it costs $15 for one adult to attend the show.

To find the mean of a number, you need to add up all the numbers listed (so, 5, -11, 7, 12, -1 and 0) and then divide it by the amount of numbers there are listed. 5 + -11 + 7 + 12 + -1 + 0 equals 12, and since there are 6 numbers you then divide 12 by 6. 12 divided 6 is 2.
So the answer is A. I hope this helped you!
