4min cool down

This is all being performed on the elliptical 5 days a week. First week it was 10 min intervals this is end of second week where i have been doing 12 min intervals and next week i will be doing 15 min intervals. I think progress so far is good as from last week to this week is a 4lb loss. I have a clean diet and train on weights 4days a week. I am just wanting to shed some excess body fat in the next 3 months for my honeymoon in dominican republic.

Im 5'10" probably 17-18% bf 200lbs and 24yrs old how much bf wouuld i need to loose to be 10-11%.
