a carnival charges $6 admission and $2.50 per ride. You have $50 to spend at the carnival. Which of the following inequalities represents the situation if r is the number of rides?
We set up our inequality using less than or equal to, since our cash is capped at $50. We use S for our :
Cost per ride * r + Admission <= 50
Plugging in our numbers, we get:
2.50r + 6 <= 50
Now, if the problem asks you to put this in terms of r, then we plug this inequality into our search engine and we get:
r <= 17.6
Since we cannot do fractional rides, we round down to 17:
r <= 17
