Lia gets paid $450 a week plus a 5% commission on her sales. she hopes to earn at least $600 a week. write an equation to represent a verbal description

Are u sure its an equation, it seems like an inequality 

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?
