Question

It costs $x for four adults' tickets. A child's ticket costs $3 less than an adult's ticket. On family night, all the tickers go for half price. Develop a formula in terms of x to calculate how much it will cost for a family of 2 adults and 3 children on family night.

Answer 1

You have x= regular adult ticket price. What's an expression for the regular child's ticket price?

Answer 2

Would it be x-$3?

Though x is the cost of 4 adult tickets so it would be x/4 right?

Answer 3

Yes, the regular child's ticket is x-3.

I'm not sure what you mean by the other part of your statement. Hold on, one step at a time. :)

So regular adult price =x, regular child price = x-3.

Now, what are expressions for the adult price, and the child price, on family night?

Answer 4

Once you have those, then you need an expression for the total cost of 2 adults and 3 children, so add them up:

cost = 2(adult family night price) + 3(children family night price)

Then just do any simplification that you can.
