The chef has less than 25.8 pounds of rice.
She takes out 5 pounds to use during the day and stores the rest in containers.
Quantity of rice stored = 25.8 - 5 = 20.8 pounds
Each container can store 2.5 pounds of rice.
Let x represent the number of containers.
The number of containers that can be filled = 20.8/2.5 = 8.32
So, the maximum number of containers the chef will be able to fill with rice is 8
