1. Answer:

   20 bags of pet food in 4 months

   Step-by-step explanation:

   3*4=12

   2*4=8

   8+12=20

   Dog food: Multiply 3 by 4 since 4 months which equals 12.

   Cat food: Next multiply 2 by 4 since 2 bags in a month which equals 8

   Finally add 8 and 12 and you will get 20 bags of pet food in 4 months.

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.
