Hurry and answer ! the selling price of an item is $495. after 6 months of not selling, it is marked down by 20%. after another 6 months of not selling, it is further marked down by 10%. find the sale price after both markdowns.

First markdown reduces the item to 0.80×495=$396.
The second markdown reduces it to 0.90×396=$356.40.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
