I NEED THE ANSWER TO THIS QUESTION ASAP - edit: IF ANYONE SEES THIS PLEASE HELP PLEASEEEE I STILL NEED THE ANSWER

the question is attached but the question is here too: at a museum, 3 adults and 5 children paid a total of $81 for admission, whereas 1 adult and 3 children paid a total of $39. what is the entrance fee for one adult and one child?

Answer 1

$21

Explanation:

You can make two equations

Let x = adult tickets

Let y = children's tickets

3x+5y=81

x+3y = 39 → x = 39-3y

Solve by substitution:

3(39 - 3y) +5y = 81

117 - 9y +5y = 81

-4y = -36

y = 9

One children's ticket is for $9

Now we can substitute y into an equation to get x.

x+3(9) =39

X+27 = 39

x =12

One adult ticket is for $12

So the price for one children ticket and one adult ticket would be 12+9 = 21.

So your answer would be C
