To calculate the dog's average weight change per week, we need to follow these steps:

1. **Add up all the weekly weight changes** to find the total weight change over the 5-week period.
2. **Divide the total weight change by 5** to get the average weekly change.

Here are the weight changes from the table:

\[
-1.5 \, \text{oz}, \, 2.2 \, \text{oz}, \, -0.8 \, \text{oz}, \, -1.6 \, \text{oz}, \, -0.6 \, \text{oz}
\]

### Step 1: Sum the weight changes
\[
-1.5 + 2.2 + (-0.8) + (-1.6) + (-0.6) = -2.3 \, \text{oz}
\]

### Step 2: Calculate the average weight change per week
\[
\text{Average} = \frac{-2.3}{5} = -0.46 \, \text{oz/week}
\]

So, the dog's average weight change per week is **-0.46 oz**, meaning it loses an average of 0.46 ounces per week.

The correct answer is **-0.46**.

### Tip:
Always ensure all numbers are added correctly, especially when dealing with negative and positive values, to avoid simple mistakes.

An overweight dog is put on a special diet. Use the table to determine the dog’s average weight change per week. The weight changes (in oz) over 5 weeks are as follows: Week 1: -1.5, Week 2: 2.2, Week 3: -0.8, Week 4: -1.6, Week 5: -0.6.

Learn how to calculate the average weight change per week for a dog on a diet using a table of weight changes over 5 weeks. This example involves adding both positive and negative weight changes and dividing the sum by the total number of weeks. Suitable for students in Grades 5-7.
