in this case, $2,900 refers to two things. one, the sales price (90%). two, the profit (108%). you should be able to get the original SALES price first. then, if he gets 8% profit, the original COST price will be 100%. so applying your formula for % decrease, you should have 16.7% as your final answer.


im not so sure so please cross check if you can! let me know if this is correct.
