I would ask the teacher if the problem is right because i attempted this problem and it doesnt work out. If u use 4 days then u get .064 which is 8/125 and isnt a possible answer. I also tried 5 days just in case and you get 1/8 so i think the problem itself may be wrong. However, I could be wrong. The picture is how (i think) the problem should be completed.
