Answer: Do not agree.
Explanation:
To determine if we agree with Marcus, we need to verify if the percentages he used on rides, video games, and batting cage add up to 100%.
Marcus used 25% of the tickets on rides and 1/2 on video games. So, the total percentage of tickets he used is:
25% + 1/2 × 100% = 25% + 50% = 75%
This means that Marcus should have used 25% of the tickets in the batting cage. If he said he used 23% of the tickets in the batting cage, then we do not agree with him.
