What did I do wrong

d. Certain merchandise items, like posters, have event dates and event schedules that are specific to a given year. That means the posters for this year's festival can only be sold once. The cost to print a poster is $4.00 and BPM plans to order 2,000 posters. i. If the posters are marked up 150% based on cost, how much money would BPM make from selling all the posters? In other words, what is BPM's revenue goal for this product? 4150%=642000=8,000cost62000=12,000revenue12,000revenue8,000cost=$4,000profit ii. If 10% of the posters will go unsold, what should BPM sell each poster for so that they meet their revenue goal? Round your answer to the nearest penny and explain your thinking. First take 2000 posters and times by 90% to get how many posters will sell. Then take the total posters bought(2000) times the cost($4) to get $8000150%=12,000/1800=$6.67 2000 (posters) 90%=1,800 posters will sell 20004=8000150%=12,000 12,000/1800=$6.67 a poster
