By the end of the summer, Tammy and Keith had mowed the same number of lawns and raked the same number of yards. Keith had met his goal of earning more than $180 but Tammy did not meet her goal of earning more than $200.

What is a possible combination of the number of lawns they could have mowed and the number of yards they could have raked? Explain how you chose the combination and why you know that combination is correct.​
