2. To find the unit price for the Smooth Cola 12-pack box at Store 1, you would divide the total price of the 12-pack box by the number of units in the box. For example, if the 12-pack box costs $5.99, the unit price would be $5.99 divided by 12, which is approximately $0.50.

3. To find the unit price for the Smooth Cola 12-pack box at Store 2, you would follow the same steps as above. If the 12-pack box costs $6.99, the unit price would be $6.99 divided by 12, which is approximately $0.58.

4. To find the unit price for the Ida Red Potatoes at Store 1, you would divide the total price of the potatoes by the weight or quantity of the potatoes. For example, if a bag of Ida Red Potatoes costs $2.99 and weighs 3 pounds, the unit price would be $2.99 divided by 3 pounds, which is approximately $0.99 per pound.

5. To find the unit price for the Ida Red Potatoes at Store 2, you would follow the same steps as above. If a bag of Ida Red Potatoes costs $3.49 and weighs 3.5 pounds, the unit price would be $3.49 divided by 3.5 pounds, which is approximately $1.00 per pound.

6. To find the unit price for the Gold Bite Tater Tots at Store 1, you would divide the total price of the tater tots by the quantity of tater tots. For example, if a bag of Gold Bite Tater Tots costs $3.99 and contains 36 tater tots, the unit price would be $3.99 divided by 36, which is approximately $0.11 per tater tot.

7. To find the unit price for the Gold Bite Tater Tots at Store 2, you would follow the same steps as above. If a bag of Gold Bite Tater Tots costs $4.49 and contains 40 tater tots, the unit price would be $4.49 divided by 40, which is approximately $0.11 per tater tot.

8. To find the unit price for the GW Carver Peanut Butter at Store 1, you would divide the total price of the peanut butter by the quantity of peanut butter. For example, if a jar of GW Carver Peanut Butter costs $2.99 and weighs 16 ounces, the unit price would be $2.99 divided by 16 ounces, which is approximately $0.19 per ounce.

9. To find the unit price for the GW Carver Peanut Butter at Store 2, you would follow the same steps as above. If a jar of GW Carver Peanut Butter costs $3.49 and weighs 18 ounces, the unit price would be $3.49 divided by 18 ounces, which is approximately $0.19 per ounce.

10. The cost equation for the Smooth Cola 12-pack, using the best priced item, can be written as C = x * 0.50, where C represents the total cost and x represents the number of 12-pack boxes purchased.

11. The cost equation for the Ida Red Potatoes, using the best priced item, can be written as C = x * 0.99, where C represents the total cost and x represents the number of pounds of potatoes purchased.

12. The cost equation for the Gold Bite Tater Tots, using the best priced item, can be written as C = x * 0.11, where C represents the total cost and x represents the number of tater tots purchased.

13. The cost equation for the GW Carver Peanut Butter, using the best priced item, can be written as C = x * 0.19, where C represents the total cost and x represents the number of ounces of peanut butter purchased.

14. The correct graph representing the proportional relationship for BOTH stores for Ida Red Potatoes would be d.

15. With proportional relationships, the graph will always make a straight line.

16. In a proportional relationship, the graph of the line always goes through the origin (0,0) because when there are no items purchased (x=0), the cost should also be zero (C=0). This represents the starting point or baseline of the relationship.
