Question

Each month, Margie's pets need 3 bags of dog food and 2 bags of cat food. How many bags of pet food would she need for 4 months?Which equation shows how to solve this problem?

Answer 1

Answer:

12

Step-by-step explanation:

since Margie needs 3 dogs food in a month you multiply 3 by 4 (3x4) and get 12. Another way you could do it is add 3 four times since she needs 3 bags in a month so, 3+3+3+3=12.

Hope it helps:)

Answer 2

Answer:

20 bags; 3 x 4 + 2 x 4 = y bags of pet food

Step-by-step explanation:

4 x 2 = 8 bags of cat food

4 x 3 = 12 bags of dog food

12 + 8 = 20 bags in total

So, we now know how many bags of pet food Margie needs for 4 months. To write an equation based on this, we need to include how many times Margie would buy each type of pet food. Which, in this case, would be 4 months. So, 4 months times 2 bags of cat food equals 8 bags of cat food, and 4 months times 3 bags of dog food equals 12 bags of dog food. This all together equals y amount of bags for pet food. In conclusion, 3 x 4 + 2 x 4 = y bags of pet food.
