Value-Mart is advertising a back to school sale on notebooks. A pack of 8 notebooks sells for $7.15, where as a 6 pack of the same brand of notebooks cost $5.25. Which is the better buy? How do you know?

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?
