I uploaded the file. Thank you !

Is it possible to make a step by step solution so k can understand the solving process

Kav10, I have made a mistake setting the deadline. The deadline is actually in 10h hours. Is it still possible for you ?

Let me see what I can do. I am out and will be home in ~5 hours. Can you please give me an exact deadline? Like is it 7 am Eastern Time?
