Math Problem Statement
Solution
Let's analyze the problem and find the correct inequality that describes the scenario.
Problem Breakdown:
- Initial Points: Kaylee gets 80 points just for signing up.
- Points per Visit: She earns 11.5 points for each visit.
- Total Points Needed: She needs at least 210 points to earn a free movie ticket.
Variables:
- Let represent the number of visits Kaylee makes to the movie theater.
Mathematical Expression:
The total points after visits is given by the sum of her initial points and the points she earns from visiting: She needs at least 210 points, so we write the inequality as:
Finding the Correct Answer:
The correct inequality is , which matches the second option in the list of answers in the image.
Would you like a step-by-step solution for solving this inequality? Here are five questions to further explore the topic:
- How many visits does Kaylee need to make if she has already earned 150 points?
- If Kaylee earns 15 points per visit instead of 11.5, how would the inequality change?
- What would happen if the number of points required for a free movie ticket increased to 250?
- If Kaylee visits the theater 5 times, how many points does she accumulate?
- Can you create a graph showing how her points increase with the number of visits?
Tip: When solving inequalities, treat them similarly to equations, but remember to reverse the inequality sign when multiplying or dividing by a negative number!
