1) Ethan earns a fixed amount of $30 a day. Oscar earns a fixed amount of $24 a day. Ethan earns an additional $4 per sale and Oscar earns an additional $6 per sale. Which answer below shows this relationship when they have the same sales? * 10 points

4n + 30 ≤ 6n + 24

6n − 30 = 4n − 24

4n + 30 = 6n + 24

4n + 30 < 6n + 24
