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.
