How much did the garage charge?
1. **State the problem:** A parking garage charges $2.50$ for the first hour and $0.50$ for each additional hour. A customer parked from 10 A.M. to 3 P.M. and gave $45$ to the attendant. We need to find how much the garage charged.
2. **Identify the necessary information:**
- Charge for the first hour: $2.50$
- Charge for each additional hour: $0.50$
- Total time parked: from 10 A.M. to 3 P.M. which is $5$ hours
- Amount given: $45$
3. **Answer to Part 1:** All the information is necessary to solve the problem because each piece helps calculate the total charge.
4. **Calculate the total charge:**
- Total hours parked: $5$
- First hour charge: $2.50$
- Additional hours: $5 - 1 = 4$
- Charge for additional hours: $4 \times 0.50 = 2.00$
5. **Total charge:**
$$\text{Total charge} = 2.50 + 2.00 = 4.50$$
6. **Compare with amount given:** The customer gave $45$, but the charge is $4.50$. This means the garage charged $4.50$ for the parking.
**Final answer:** The garage charged $4.50$ for parking from 10 A.M. to 3 P.M.
