Let's break down the problem step-by-step to determine the number of calls made in a day.
1. Identify the number of calls made before noon:
- The problem states that there are 365 calls made before noon.
2. Identify the number of calls made after noon:
- The problem also states that 189 calls are made after noon.
3. Calculate the total number of calls made in a day:
- To find the total number of calls made in a day, we need to sum the calls made before noon and the calls made after noon.
- Mathematically, this can be represented as:
- Total number of calls = Number of calls made before noon + Number of calls made after noon
- So, we have:
- Total number of calls = 365 + 189
4. Sum the numbers:
- Adding 365 and 189 gives 554.
Thus, the total number of calls made in a day is 554.
