Final answer:
The cost for the MDTABBS plan is $2 per trip for drivers who take at least 25 trips in a calendar month and use E-ZPass.
Step-by-step explanation:
The Memorial Bridge (Bay Bridge) Shoppers Discount (MDTABBS) plan is a program that offers discounted toll rates to frequent shoppers at the Bay Bridge. The cost for this plan is $2 per trip for drivers who take at least 25 trips in a calendar month. For drivers who take less than 25 trips in a month, the regular toll rate of $4 applies.
For example, if a driver takes 30 trips across the Bay Bridge in a given month, they would qualify for the MDTABBS plan. Their total cost for that month would be $60 (30 trips x $2 per trip).
It is important to note that the MDTABBS plan is only available to drivers who use E-ZPass, a toll collection system that automates the payment process. Drivers can sign up for the MDTABBS plan by logging into their E-ZPass account and selecting the appropriate option.
