Ihate people who scam so if you get this wrong and you don't take more than 1 monute i will report you. 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.
how many containers will she be able to put 2.5 pounds of rice in?

Shef has less than 25.8 pounds of rice
take out 5
25.8-5=20.8

now has less than 20.8

each container hsa 2.5 pounds of race
if we assume she has 20.8 pounds then
total weight=weight per container times number of containers (x)
20.8=2.5 times x
20.8=2.5x
divide both sides by 2.5
8.32=x
we 0.32 container doesn't count so round down
8 containers (if she has at least 20lb of rice but less than 20.8)

answer is 8 containers
