The answer is $10 per adult ticket, and $7 per child ticket. Now lets figure out how to get to that answer. Let's create a chart to help visualize this.
- - - - -A- - - - - C- - - - -T- - - - -
: 2 : 4 : $48 :
: 5 : 2 : $64 : Key:
: : : : A = Adult ( The Y)
: : : : C = Child ( The X)
: : : : T= Total
When we look at it, the total cost is less then what the adult would be when multiplied by 10, and you WOULD have to add the children cost to the adult cost, so lets try it.
Lets do the 2 adult tickets first, 2 x 10 is 20. Now we do 48 - 20 to get how much the cost of the children's 4 needs to equal. We get 28 as the answer. Now we have to do 28 divided by 4, we get 7 as that answer.
Now lets plug that in to the $64 problem and see if that gets us the correct answer.
So the amount of adult tickets for this problem is 5, so we do 5 x 1 which is 50.
Now the amount of children tickets is 2, so lets do 2 x 7, which equals 14.
Now to test if it gets us the correct answer, to do that we do 50 + 14, that equals what we want it to, 64.
Therefor, the correct answer is $10 per adult ticket, and $7 per child ticket.
Hope this helps!
