Graph: a line increasing from the bottom-left to the top-right on a grid, with marked points around $(1, 20)$, $(2, 40)$, and $(3, 60)$; position_hint = top-right
1. **State the problem:** We need to find the unit rate for Jenny’s Jean Store, which means finding the cost per pair of jeans.
2. **Identify the data points:** From the table and graph, we have pairs of jeans and their total cost:
- $(1, 20)$
- $(2, 40)$
- $(3, 60)$
3. **Formula for unit rate:** The unit rate is calculated as
$$\text{Unit Rate} = \frac{\text{Total Cost}}{\text{Number of Pairs}}$$
4. **Calculate the unit rate using the first point:**
$$\text{Unit Rate} = \frac{20}{1} = 20$$
5. **Verify with other points:**
$$\frac{40}{2} = 20$$
$$\frac{60}{3} = 20$$
6. **Interpretation:** The cost per pair of jeans is $20$.
**Final answer:** The unit rate for Jenny’s Jean Store is $20$ dollars per pair of jeans.
