Answer 1

To find out how many whole gallons of milk you can buy for $14 at each store, we can start by writing an equation and then solving it step by step.

**Step 1: Identify the price of a gallon of milk at each store.**

- At Krogers, the price of a gallon of milk is **$3.39**.
- At Publix, the price of a gallon of milk is **$3.22**.

**Step 2: Write an equation for each store.**

Let \( x \) be the number of gallons of milk you can buy. The equation can be set up as follows:

For Krogers:
\[
3.39x \leq 14
\]

For Publix:
\[
3.22x \leq 14
\]

**Step 3: Solve each equation for \( x \).**

**Krogers:**
\[
x \leq \frac{14}{3.39} \approx 4.13
\]
Since you can only buy whole gallons, you need to round down. So, at Krogers, you can buy **4 gallons** of milk.

**Publix:**
\[
x \leq \frac{14}{3.22} \approx 4.34
\]
Again, rounding down means you can buy **4 gallons** of milk at Publix as well.

**Step 4: Conclusion**

In conclusion, you can buy **4 whole gallons of milk** at both Krogers and Publix for $14.
