Given that each bus ride is $3, and that assuming the takes the ride twice a day,
[tex]\begin{gathered} \text{Amount spent a day on bus ride = 2 }\times\text{ \$3} \\ =\text{ \$6} \end{gathered}[/tex]If he takes the ride in the same manner for 11 days,
[tex]\begin{gathered} \text{Amount spent in 11 days = 11 }\times\text{ \$6} \\ =\text{ \$ 66} \end{gathered}[/tex]Thus, he needs $66 to ride the bus twice for 11 days.
Since Clay has $50, he will not be able to ride the bus twice for 11 days.
Hence, the correct answer is False
