Answer: C: 21.38%Step-by-step explanation:Step-by-step explanation: Knowing the apr was 0 for the first 60 days, and 23.19% for the rest of the days, the equation we need to do is:R = (1 + r/(365) )^(D) - 1Where R is the apr (in decimal form), we have 0 for the first 60 days, and 0.2319 for the other 305 days.D is the number of days that is applied, so we have two parts:R = (( 1 + 0/365)^60 - 1 ) + ((1 + 0.2319/365)^305 - 1) = 0.21375That can be rounded up to 0.2138.Now, we multiply this number by 100% and we get 21.38%so the right answer is C.
