Each toothbrush will cost $2.58 if the dentist office orders less than 50 toothbrushes. However, if the dentist orders 50 or more toothbrushes, then each toothbrush will only cost $1.24. Write a piecewise linear function for the total cost, C(t), in dollars, as a function of the number of toothbrushes ordered, t.
