Question

Luna had a 50$ when she got to the carnival.after riding 12 rides, she had 26$ left .what equation can be used to represent this situation ?

Answer 1

Let's see... We don't know how much the rides cost, so we can use x to represent that.

26=50-12x
This is the equation. There we go!
Now, if you want to take it a step further and solve for x:
26-50=50-50-12x
-24=-12x
24 = 12x
x=2
So each ride cost $2.
