Eve earns 20% commission as a salesperson. She sold an aquarium that cost 56 dollars. How much commission did Eve earn?​

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

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?
