Thank you ^_^

I agree :)

Two admissions at $18 each:  $36
Two ice creams at $1.50 each : $3
------------------------------
Total so far $39
Minus $10 from Amy leaves $29 for Mike to pay for just admissions and ice creams... but Mike also bought a soda and paid $30.25 total, so he must have paid an extra $1.25 for the soda.

You're welcome, glad to help.

If you're doing algebra, you could also set it up that way:

2 admissions + 2 ice creams + 1 soda - $10 from Amy = Total paid by Mike

2 * 18   +   2 * 1.50   +   x   -   10   =   30.25

And then simplify and solve for x, the price of a soda.

It would be the same thing though... just another way to set it up.
