Answer 1

Let’s see if we can buy 3 dozen eggs and a frozen pizza from either Kroger or Publix with $20.

Kroger:

• Eggs: $2.29 per dozen, so 3 dozen = 3 x $2.29 = $6.87
• Frozen pizza: $8.49

Total at Kroger: $6.87 + $8.49 = $15.36

Publix:

• Eggs: $2.24 per dozen, so 3 dozen = 3 x $2.24 = $6.72
• Frozen pizza: $9.24

Total at Publix: $6.72 + $9.24 = $15.96

You have $20, so you can buy 3 dozen eggs and a frozen pizza from both Kroger and Publix. You’ll have some money left over from both stores!

Answer 2

How many whole gallons of milk can you buy for $14 at each store? Remember, you can't buy part of a gallon. Write and solve an equation to find your answer.

Answer 3

To find out how many whole gallons of milk you can buy for $14 at each store, we'll use the equation:

\[ \text{Number of gallons} = \frac{\text{Total money}}{\text{Price per gallon}} \]

For Kroger:

• Price of a gallon of milk = $3.39

\[ \text{Number of gallons at Kroger} = \frac{14}{3.39} \approx 4.13 \]

Since you can’t buy part of a gallon, you can buy 4 gallons of milk at Kroger.

For Publix:

• Price of a gallon of milk = $3.22

\[ \text{Number of gallons at Publix} = \frac{14}{3.22} \approx 4.35 \]

Again, since you can’t buy part of a gallon, you can buy 4 gallons of milk at Publix too.

In Conclusion: You can buy 4 whole gallons of milk at both Kroger and Publix with $14.
