Answer:
Yes , it would be better to continue to pay daily .
Reason
As given
Martha is taking the bus into work 3 times a week (12 times a month) for $4.50 a day.
Buy the monthly pass for $59 .
Than
Cost that Martha pays 12 times a month = 12 × 4.50
= $ 54
As the cost that Martha pays 12 times a month is less than the cost of monthly pass .
Therefore it would be better to continue to pay daily .
