Akira could go on \( 0,1,2,3,4,5,6 \), or 7 thrill rides. Akira's sister from the Example is too young to ride alone. Akira uses tokens to go on the 5 kiddie rides with her. Now how many thrill rides can he go on? Explain.

To determine how many thrill rides Akira can go on, let's break down the information provided: 1. **Total Thrill Rides Available:** Akira has the option to go on **0 to 7 thrill rides**. This implies he has a total of **7 tokens** available for thrill rides. 2. **Using Tokens for Kiddie Rides:** Akira uses some of these tokens to go on **5 kiddie rides** with his sister. Since each ride (whether thrill or kiddie) requires a token, he uses **5 tokens** for the kiddie rides. 3. **Remaining Tokens for Thrill Rides:** After using 5 tokens for the kiddie rides, Akira has: \[ \text{Total Tokens} - \text{Tokens Used for Kiddie Rides} = 7 - 5 = 2 \text{ tokens} \] 4. **Thrill Rides Akira Can Go On:** With the remaining **2 tokens**, Akira can go on **2 thrill rides**. **Conclusion:** Akira can go on **2 thrill rides** after using 5 tokens for the kiddie rides.
