You and 3 friends plan to split the cost in dollars of a large bag of popcorn at a movie. Write a function that describes the cost for each person P(b) as a function of the cost per bag b.

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?
