How can you determine the sale price if you are given the regular price and the percent of markdown?

You convert the percentage into a fraction, multiply this by the sale price, then subtract by this number. Example: Price is $20.00 and the markdown is 20%. First make 20% a decimal by dividing by 100 to get 0.2. Multiply 0.2 by 20 to get 4. Now take 4 and subtract it from 20 to get 16. So a markdown of 20% of a $20.00 item is $16.00

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?
