Answer:
The pellet will last after 12 days
Explanation:
* Lets change the story problem to equations to solve it
- There is a pound of guinea pig pellets
- One pound of pellets is about three cups of food
- Each guinea pig eats 1/4 cup of pellets a day
* Lets use these information to solve the problem
∵ One pound of guinea = 3 cups of food
∵ The guinea pig eats 1/4 cup a day
- The pig can finish one cup in four days
∵ The number of days = number of cups ÷ the eaten in a day
∵ The number of cup = 3 cups
∵ The eaten pellets in a day = 1/4
∴ The number of days = 3 ÷ 1/4 = 3 × 4/1 = 12 days
* The pellet will last after 12 days
