Some counties in New Jersey missed many school days one year due to a huge blizzard.  A proposed solution for making up those days was to add time to each school day for a portion of the year.  It was proposed that in order to make up a 6 hour school day, 30 minutes would be added to each day.

Let d = # days, T(d) = the time of a school day, in hours, after d days of making up time.  Which mathematical model most accurately represents this situation?

• T(d) = 6(0.5)^t
• T(d)=(t-0.5)²+6
• T(d) = 0.5t + 6
• T(d) = 0.5 + 6t
