At the local store Seabrook food cost $1.90 each and neon tetras cost $2.15 each. If Mrs. Thile Bach 15 fish for total cost of $30.25 not including tax how many of each type of fish did she buy?

Iwould say rat and vsu but i’m not 100% sure

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?
