Dolores and four friends went to a buffet dinner. the total cost was at most $130 including the $20 dollar tip they left. how much did each pay for the buffet? i need an inequality

So the actual meal was at most 130 dollars they paid minus the 20 dolars tip: 130-20=110 dollars.

it was 5 people: Dolores+5 friends, who presumably all paid the same (buffet).

then we have to divide the 110 among the 5 people: it's 110/5=22

so each of them paid at most 22 dollars:

x (the amount they paid)≤22
