Mabel just got a new credit card that offers both an introductory and a standard apr. if the standard apr is 15.5%, which of the following rates would most likely be the introductory apr?

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

The apr stands for "annual percentage rate". if mabel just got a new credit card that offers both an introductory and a standard apr of 15.5%, is she wants to know and determine the introductory rate, well the answer should be less than the standard rate (15.5%).

the answer should be less any value less than 15.5%. if there is 5.5% in choices, then that is the answer since it is smaller than 15.5%.
