Bort wants to make money selling tacos. He sells 25 tacos on the first day. He then sells 12 tacos each day after that.

Write an explicit formula to model this situation.

The explicit formula to model this situation is:

T(n) = 25 + 12(n-1)

where T(n) represents the total number of tacos sold on the nth day, and n represents the day number.
