Yeah, you got it right, good job. You let the quantity you're looking for, the price of the adult tickets, be x. Then, the cost of 3 of those is 3x, and the cost of 4 child tickets is 4x/2, just like you said, because child tickets are half the cost.

So, do you see how to solve that equation and get the right answer?

anonymous · Answer

its C

anonymous · Answer

How?

anonymous · Answer

So, first simplify 4x/2: that's just 2x. Then rewrite your equation:

3x + 2x = 8

Combine like terms

5x = 8

And isolate x, by dividing by 5 on both sides

x = 8/5 = 1.6

And that's C.

Oh...

Does that make sense?

anonymous · Answer

Yerp. But is 1.6 the adult fair, right?

anonymous · Answer

Right, because that's what x was. You could find a different equation where x is the child fare, and then you'd solve for that instead.
