A 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. Each container has 2.5 pounds of rice. Let x represent the number of containers. What is the maximum number of containers the chef will be able to fill with rice? 13 12 8 7

Answers

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

The answer should be eight. Hope this helps! :)
