What is the range in the number of deliveries?



Answer :

To determine the range of deliveries that Alex makes in a week, we need to follow a series of steps. Here is the detailed solution:

1. Identify the number of deliveries for each day:
- Monday: 189 deliveries
- Tuesday: 125 deliveries
- Wednesday: 102 deliveries
- Thursday: 96 deliveries
- Friday: 109 deliveries

2. Determine the maximum number of deliveries in a single day.
- By comparing the numbers above, we see that the maximum number of deliveries is 189 (on Monday).

3. Determine the minimum number of deliveries in a single day.
- By comparing the same numbers, we find that the minimum number of deliveries is 96 (on Thursday).

4. Calculate the range in the number of deliveries.
- The range is the difference between the maximum and minimum number of deliveries.
- So, we subtract the minimum number of deliveries from the maximum number of deliveries:
[tex]\[ \text{Range} = \text{Maximum Deliveries} - \text{Minimum Deliveries} \][/tex]
- Plugging in the values:
[tex]\[ \text{Range} = 189 - 96 \][/tex]
- Therefore, the range in the number of deliveries is 93.

In conclusion, the maximum number of deliveries Alex makes in a single day is 189, the minimum number is 96, and the range in the number of deliveries throughout the week is 93.
